/* src/include/pg_config.h.in. Generated from configure.in by autoheader. */
Version number now set in configure, available through Makefile.global and config.h. Adjusted all referring code. Scrapped pg_version and changed initdb accordingly. Integrated src/utils/version.c into src/backend/utils/init/miscinit.c. Changed all callers. Set version number to `7.1devel'. (Non-numeric version suffixes now allowed.)

Support alternate storage scheme of 64-bit integer for date/time types. Use "--enable-integer-datetimes" in configuration to use this rather than the original float8 storage. I would recommend the integer-based storage for any platform on which it is available. We perhaps should make this the default for the production release. Change timezone(timestamptz) results to return timestamp rather than a character string. Formerly, we didn't have a way to represent timestamps with an explicit time zone other than freezing the info into a string. Now, we can reasonably omit the explicit time zone from the result and return a timestamp with values appropriate for the specified time zone. Much cleaner, and if you need the time zone in the result you can put it into a character string pretty easily anyway. Allow fractional seconds in date/time types even for dates prior to 1BC. Limit timestamp data types to 6 decimal places of precision. Just right for a micro-second storage of int8 date/time types, and reduces the number of places ad-hoc rounding was occuring for the float8-based types. Use lookup tables for precision/rounding calculations for timestamp and interval types. Formerly used pow() to calculate the desired value but with a more limited range there is no reason to not type in a lookup table. Should be *much* better performance, though formerly there were some optimizations to help minimize the number of times pow() was called. Define a HAVE_INT64_TIMESTAMP variable. Based on the configure option "--enable-integer-datetimes" and the existing internal INT64_IS_BUSTED. Add explicit date/interval operators and functions for addition and subtraction. Formerly relied on implicit type promotion from date to timestamp with time zone. Change timezone conversion functions for the timetz type from "timetz()" to "timezone()". This is consistant with other time zone coersion functions for other types. Bump the catalog version to 200204201. Fix up regression tests to reflect changes in fractional seconds representation for date/times in BC eras. All regression tests pass on my Linux box.

Remove the recently added USE_SEGMENTED_FILES option, and indeed remove all support for a nonsegmented mode from md.c. Per recent discussions, there doesn't seem to be much value in a "never segment" option as opposed to segmenting with a suitably large segment size. So instead provide a configure-time switch to set the desired segment size in units of gigabytes. While at it, expose a configure switch for BLCKSZ as well. Zdenek Kotala

Rearrange handling of MAXBACKENDS a little bit. The default setting of MAXBACKENDS is now 1024, since all it's costing is about 32 bytes of memory per array slot. configure's --with-maxbackends switch now controls DEF_MAXBACKENDS which is simply the default value of the postmaster's -N switch. Thus, the out-of-the-box configuration will still limit you to 64 backends, but you can go up to 1024 backends simply by restarting the postmaster with a different -N switch --- no rebuild required.

Start using flexible array members Flexible array members are a C99 feature that avoids "cheating" in the declaration of variable-length arrays at the end of structs. With Autoconf support, this should be transparent for older compilers. We start with one use in gist.h because gcc 4.6 started to raise a warning there. Over time, it can be expanded to other places in the source, but they will likely need some review of sizeof and offsetof usage. The current change in gist.h appears to be safe in this regard.

instead. Don't use 'offsetof (struct s, d[0])', as this doesn't work with

Allow float8, int8, and related datatypes to be passed by value on machines where Datum is 8 bytes wide. Since this will break old-style C functions (those still using version 0 calling convention) that have arguments or results of these types, provide a configure option to disable it and retain the old pass-by-reference behavior. Likewise, provide a configure option to disable the recently-committed float4 pass-by-value change. Zoltan Boszormenyi, plus configurability stuff by me.

Write psql's ~/.psql_history file using history_truncate_file() and append_history(), if libreadline is new enough to have those functions (they seem to be present at least since 4.2; but libedit may not have them). This gives significantly saner behavior when two or more sessions overlap in their use of the history file; although having two sessions exit at just the same time is still perilous to your history. The behavior of \s remains unchanged, ie, overwrite whatever was there. Per bug #5052 from Marek Wójtowicz.

Add a basic atomic ops API abstracting away platform/architecture details. Several upcoming performance/scalability improvements require atomic operations. This new API avoids the need to splatter compiler and architecture dependent code over all the locations employing atomic ops. For several of the potential usages it'd be problematic to maintain both, a atomics using implementation and one using spinlocks or similar. In all likelihood one of the implementations would not get tested regularly under concurrency. To avoid that scenario the new API provides a automatic fallback of atomic operations to spinlocks. All properties of atomic operations are maintained. This fallback - obviously - isn't as fast as just using atomic ops, but it's not bad either. For one of the future users the atomics ontop spinlocks implementation was actually slightly faster than the old purely spinlock using implementation. That's important because it reduces the fear of regressing older platforms when improving the scalability for new ones. The API, loosely modeled after the C11 atomics support, currently provides 'atomic flags' and 32 bit unsigned integers. If the platform efficiently supports atomic 64 bit unsigned integers those are also provided. To implement atomics support for a platform/architecture/compiler for a type of atomics 32bit compare and exchange needs to be implemented. If available and more efficient native support for flags, 32 bit atomic addition, and corresponding 64 bit operations may also be provided. Additional useful atomic operations are implemented generically ontop of these. The implementation for various versions of gcc, msvc and sun studio have been tested. Additional existing stub implementations for * Intel icc * HUPX acc * IBM xlc are included but have never been tested. These will likely require fixes based on buildfarm and user feedback. As atomic operations also require barriers for some operations the existing barrier support has been moved into the atomics code.

Here is the patch with memory leak checker. This checker allow detect in-chunk leaks, overwrite-next-chunk leaks and overwrite block-freeptr leaks. A in-chunk leak --- if something overwrite space after wanted (via palloc() size, but it is still inside chunk. For example x = palloc(12); /* create 16b chunk */ memset(x, '#', 13); this leak is in the current source total invisible, because chunk is 16b and leak is in the "align space". For this feature I add data_size to StandardChunk, and all memory which go from AllocSetAlloc() is marked as 0x7F. The MemoryContextCheck() is compiled '#ifdef USE_ASSERT_CHECKING'. I add this checking to 'tcop/postgres.c' and is active after each backend query, but it is probably not sufficient, because some MemoryContext exist only during memory processing --- will good if someone who known where it is needful (Tom:-) add it for others contexts; A problem in the current source is that we have still some malloc() allocation that is not needful and this allocation is total invisible for all context routines. For example Dllist in backend (pretty dirty it is in catcache where values in Dllist are palloc-ed, but list is malloc-ed). --- and BTW. this Dllist design stand in the way for query cache :-) Tom, if you agree I start replace some mallocs. BTW. --- Tom, have you idea for across transaction presistent allocation for SQL functions? (like regex - now it is via malloc) I almost forget. I add one if() to AllocSetAlloc(), for 'size' that are greater than ALLOC_BIGCHUNK_LIMIT is not needful check AllocSetFreeIndex(), because 'fidx' is always 'ALLOCSET_NUM_FREELISTS - 1'. It a little brisk up allocation for very large chunks. Right? Karel

Support fls(). The immediate impetus for this is that Noah Misch's patch to elide unnecessary table and index rebuilds when changing typmod for temporal types uses it; and this is extracted from that patch, with some further commentary by me. But it seems logically separate from the remainder of the patch, so I'm committing it separately; this is not the first time someone has wanted fls() in the backend and probably won't be the last. If we end up using this in more performance-critical spots it may be worthwhile to add some architecture-specific optimizations to our src/port version of fls() - e.g. any x86 platform can implement this using the assembly instruction BSRL. But performance won't matter a bit for assessing typmod changes, so I'm not worried about that right now.

Add a basic atomic ops API abstracting away platform/architecture details. Several upcoming performance/scalability improvements require atomic operations. This new API avoids the need to splatter compiler and architecture dependent code over all the locations employing atomic ops. For several of the potential usages it'd be problematic to maintain both, a atomics using implementation and one using spinlocks or similar. In all likelihood one of the implementations would not get tested regularly under concurrency. To avoid that scenario the new API provides a automatic fallback of atomic operations to spinlocks. All properties of atomic operations are maintained. This fallback - obviously - isn't as fast as just using atomic ops, but it's not bad either. For one of the future users the atomics ontop spinlocks implementation was actually slightly faster than the old purely spinlock using implementation. That's important because it reduces the fear of regressing older platforms when improving the scalability for new ones. The API, loosely modeled after the C11 atomics support, currently provides 'atomic flags' and 32 bit unsigned integers. If the platform efficiently supports atomic 64 bit unsigned integers those are also provided. To implement atomics support for a platform/architecture/compiler for a type of atomics 32bit compare and exchange needs to be implemented. If available and more efficient native support for flags, 32 bit atomic addition, and corresponding 64 bit operations may also be provided. Additional useful atomic operations are implemented generically ontop of these. The implementation for various versions of gcc, msvc and sun studio have been tested. Additional existing stub implementations for * Intel icc * HUPX acc * IBM xlc are included but have never been tested. These will likely require fixes based on buildfarm and user feedback. As atomic operations also require barriers for some operations the existing barrier support has been moved into the atomics code.

Use __sync_lock_test_and_set() for spinlocks on ARM, if available. Historically we've used the SWPB instruction for TAS() on ARM, but this is deprecated and not available on ARMv6 and later. Instead, make use of a GCC builtin if available. We'll still fall back to SWPB if not, so as not to break existing ports using older GCC versions. Eventually we might want to try using __sync_lock_test_and_set() on some other architectures too, but for now that seems to present only risk and not reward. Back-patch to all supported versions, since people might want to use any of them on more recent ARM chips. Martin Pitt

I use this prefix , when configure ask me for "Additional directories to search for include files" . ( because there a conflict in the header when you compile psql.c ) In this case, you must permut the sequence of directive -I . Erwan MAS

More cleanups. I can now compile without PORTNAME being defined n Makefile.global. End result, if all goes well, should allow for much easier porting, since there will no longer be a concept of a "port". Most, if not everything, *should* be determined by configure, or by the compiler itself. Still work to be done though :)

Make configure probe for mbstowcs_l as well as wcstombs_l. We previously supposed that any given platform would supply both or neither of these functions, so that one configure test would be sufficient. It now appears that at least on AIX this is not the case ... which is likely an AIX bug, but nonetheless we need to cope with it. So use separate tests. Per bug #6758; thanks to Andrew Hastie for doing the followup testing needed to confirm what was happening. Backpatch to 9.1, where we began using these functions.

Use mutex hint bit in PPC LWARX instructions, where possible. The hint bit makes for a small but measurable performance improvement in access to contended spinlocks. On the other hand, some PPC chips give an illegal-instruction failure. There doesn't seem to be a completely bulletproof way to tell whether the hint bit will cause an illegal-instruction failure other than by trying it; but most if not all 64-bit PPC machines should accept it, so follow the Linux kernel's lead and assume it's okay to use it in 64-bit builds. Of course we must also check whether the assembler accepts the command, since even with a recent CPU the toolchain could be old. Patch by Manabu Ori, significantly modified by me.

Cope with Readline's failure to track SIGWINCH events outside of input. It emerges that libreadline doesn't notice terminal window size change events unless they occur while collecting input. This is easy to stumble over if you resize the window while using a pager to look at query output, but it can be demonstrated without any pager involvement. The symptom is that queries exceeding one line are misdisplayed during subsequent input cycles, because libreadline has the wrong idea of the screen dimensions. The safest, simplest way to fix this is to call rl_reset_screen_size() just before calling readline(). That causes an extra ioctl(TIOCGWINSZ) for every command; but since it only happens when reading from a tty, the performance impact should be negligible. A more valid objection is that this still leaves a tiny window during entry to readline() wherein delivery of SIGWINCH will be missed; but the practical consequences of that are probably negligible. In any case, there doesn't seem to be any good way to avoid the race, since readline exposes no functions that seem safe to call from a generic signal handler --- rl_reset_screen_size() certainly isn't. It turns out that we also need an explicit rl_initialize() call, else rl_reset_screen_size() dumps core when called before the first readline() call. rl_reset_screen_size() is not present in old versions of libreadline, so we need a configure test for that. (rl_initialize() is present at least back to readline 4.0, so we won't bother with a test for it.) We would need a configure test anyway since libedit's emulation of libreadline doesn't currently include such a function. Fortunately, libedit seems not to have any corresponding bug. Merlin Moncure, adjusted a bit by me

Add fsync capability to initdb, and use sync_file_range() if available. Historically we have not worried about fsync'ing anything during initdb (in fact, initdb intentionally passes -F to each backend launch to prevent it from fsync'ing). But with filesystems getting more aggressive about caching data, that's not such a good plan anymore. Make initdb do a pass over the finished data directory tree to fsync everything. For testing purposes, the -N/--nosync flag can be used to restore the old behavior. Also, testing shows that on Linux, sync_file_range() is much faster than posix_fadvise() for hinting to the kernel that an fsync is coming, apparently because the latter blocks on a rather small request queue while the former doesn't. So use this function if available in initdb, and also in the backend's pg_flush_data() (where it currently will affect only the speed of CREATE DATABASE's cloning step). We will later make pg_regress invoke initdb with the --nosync flag to avoid slowing down cases such as "make check" in contrib. But let's not do so until we've shaken out any portability issues in this patch. Jeff Davis, reviewed by Andres Freund

The attached patch enables PostgreSQL CVS to build cleanly under Cygwin when built against readline 4.2. Specifically, it handles the deprecation of filename_completion_function() with preference for rl_filename_completion_function() Although, I was motivated by Cygwin support, IMO this patch is appropriate for all platforms. To quote from the readline source: #if 0 /* Backwards compatibility (compat.c). These will go away sometime. */ ... extern READLINE_EXPORT(char, *filename_completion_function) ... #endif Note that this patch is modeled after the one by Peter Eisentraut for completion_matches(): http://www.ca.postgresql.org/~petere/readline42.html I tested this patch under the following environments: Cygwin with readline 4.1 Cygwin with readline 4.2 Linux with readline 2.2.1 Linux with readline 4.2 and it behaved as expected.

Replace use of credential control messages with getsockopt(LOCAL_PEERCRED). It turns out the reason we hadn't found out about the portability issues with our credential-control-message code is that almost no modern platforms use that code at all; the ones that used to need it now offer getpeereid(), which we choose first. The last holdout was NetBSD, and they added getpeereid() as of 5.0. So far as I can tell, the only live platform on which that code was being exercised was Debian/kFreeBSD, ie, FreeBSD kernel with Linux userland --- since glibc doesn't provide getpeereid(), we fell back to the control message code. However, the FreeBSD kernel provides a LOCAL_PEERCRED socket parameter that's functionally equivalent to Linux's SO_PEERCRED. That is both much simpler to use than control messages, and superior because it doesn't require receiving a message from the other end at just the right time. Therefore, add code to use LOCAL_PEERCRED when necessary, and rip out all the credential-control-message code in the backend. (libpq still has such code so that it can still talk to pre-9.1 servers ... but eventually we can get rid of it there too.) Clean up related autoconf probes, too. This means that libpq's requirepeer parameter now works on exactly the same platforms where the backend supports peer authentication, so adjust the documentation accordingly.

Attached is a patch that uses autoconf to determine whether there is a working 64-bit-int type available. In playing around with it on my machine, I found that gcc provides perfectly fine support for "long long" arithmetic ... but sprintf() and sscanf(), which are system-supplied, don't work :-(. So the autoconf test program does a cursory test on them too. If we find that a lot of systems are like this, it might be worth the trouble to implement binary<->ASCII conversion of int64 ourselves rather than relying on sprintf/sscanf to handle the data type. regards, tom lane

Fix char2wchar/wchar2char to support collations properly. These functions should take a pg_locale_t, not a collation OID, and should call mbstowcs_l/wcstombs_l where available. Where those functions are not available, temporarily select the correct locale with uselocale(). This change removes the bogus assumption that all locales selectable in a given database have the same wide-character conversion method; in particular, the collate.linux.utf8 regression test now passes with LC_CTYPE=C, so long as the database encoding is UTF8. I decided to move the char2wchar/wchar2char functions out of mbutils.c and into pg_locale.c, because they work on wchar_t not pg_wchar_t and thus don't really belong with the mbutils.c functions. Keeping them where they were would have required importing pg_locale_t into pg_wchar.h somehow, which did not seem like a good plan.

Speed up CRC calculation using slicing-by-8 algorithm. This speeds up WAL generation and replay. The new algorithm is significantly faster with large inputs, like full-page images or when inserting wide rows. It is slower with tiny inputs, i.e. less than 10 bytes or so, but the speedup with longer inputs more than make up for that. Even small WAL records at least have 24 byte header in the front. The output is identical to the current byte-at-a-time computation, so this does not affect compatibility. The new algorithm is only used for the CRC-32C variant, not the legacy version used in tsquery or the "traditional" CRC-32 used in hstore and ltree. Those are not as performance critical, and are usually only applied over small inputs, so it seems better to not carry around the extra lookup tables to speed up those rare cases. Abhijit Menon-Sen

Improve handling of ereport(ERROR) and elog(ERROR). In commit 71450d7fd6c7cf7b3e38ac56e363bff6a681973c, we added code to inform suitably-intelligent compilers that ereport() doesn't return if the elevel is ERROR or higher. This patch extends that to elog(), and also fixes a double-evaluation hazard that the previous commit created in ereport(), as well as reducing the emitted code size. The elog() improvement requires the compiler to support __VA_ARGS__, which should be available in just about anything nowadays since it's required by C99. But our minimum language baseline is still C89, so add a configure test for that. The previous commit assumed that ereport's elevel could be evaluated twice, which isn't terribly safe --- there are already counterexamples in xlog.c. On compilers that have __builtin_constant_p, we can use that to protect the second test, since there's no possible optimization gain if the compiler doesn't know the value of elevel. Otherwise, use a local variable inside the macros to prevent double evaluation. The local-variable solution is inferior because (a) it leads to useless code being emitted when elevel isn't constant, and (b) it increases the optimization level needed for the compiler to recognize that subsequent code is unreachable. But it seems better than not teaching non-gcc compilers about unreachability at all. Lastly, if the compiler has __builtin_unreachable(), we can use that instead of abort(), resulting in a noticeable code savings since no function call is actually emitted. However, it seems wise to do this only in non-assert builds. In an assert build, continue to use abort(), so that the behavior will be predictable and debuggable if the "impossible" happens.

Improve handling of ereport(ERROR) and elog(ERROR). In commit 71450d7fd6c7cf7b3e38ac56e363bff6a681973c, we added code to inform suitably-intelligent compilers that ereport() doesn't return if the elevel is ERROR or higher. This patch extends that to elog(), and also fixes a double-evaluation hazard that the previous commit created in ereport(), as well as reducing the emitted code size. The elog() improvement requires the compiler to support __VA_ARGS__, which should be available in just about anything nowadays since it's required by C99. But our minimum language baseline is still C89, so add a configure test for that. The previous commit assumed that ereport's elevel could be evaluated twice, which isn't terribly safe --- there are already counterexamples in xlog.c. On compilers that have __builtin_constant_p, we can use that to protect the second test, since there's no possible optimization gain if the compiler doesn't know the value of elevel. Otherwise, use a local variable inside the macros to prevent double evaluation. The local-variable solution is inferior because (a) it leads to useless code being emitted when elevel isn't constant, and (b) it increases the optimization level needed for the compiler to recognize that subsequent code is unreachable. But it seems better than not teaching non-gcc compilers about unreachability at all. Lastly, if the compiler has __builtin_unreachable(), we can use that instead of abort(), resulting in a noticeable code savings since no function call is actually emitted. However, it seems wise to do this only in non-assert builds. In an assert build, continue to use abort(), so that the behavior will be predictable and debuggable if the "impossible" happens.

Use Intel SSE 4.2 CRC instructions where available. Modern x86 and x86-64 processors with SSE 4.2 support have special instructions, crc32b and crc32q, for calculating CRC-32C. They greatly speed up CRC calculation. Whether the instructions can be used or not depends on the compiler and the target architecture. If generation of SSE 4.2 instructions is allowed for the target (-msse4.2 flag on gcc and clang), use them. If they are not allowed by default, but the compiler supports the -msse4.2 flag to enable them, compile just the CRC-32C function with -msse4.2 flag, and check at runtime whether the processor we're running on supports it. If it doesn't, fall back to the slicing-by-8 algorithm. (With the common defaults on current operating systems, the runtime-check variant is what you get in practice.)

Add, optional, support for 128bit integers. We will, for the foreseeable future, not expose 128 bit datatypes to SQL. But being able to use 128bit math will allow us, in a later patch, to use 128bit accumulators for some aggregates; leading to noticeable speedups over using numeric. So far we only detect a gcc/clang extension that supports 128bit math, but no 128bit literals, and no *printf support. We might want to expand this in the future to further compilers; if there are any that that provide similar support.

Autoconfiscate selection of 64-bit int type for 64-bit large object API. Get rid of the fundamentally indefensible assumption that "long long int" exists and is exactly 64 bits wide on every platform Postgres runs on. Instead let the configure script select the type to use for "pg_int64". This is a bit of a pain in the rear since we do not want to pollute client namespace with all the random symbols that pg_config.h defines; instead we have to create a separate generated header file, "pg_config_ext.h". But now that the infrastructure is there, we might have the ability to add some other stuff that's long been wanting in this area.

Allow use of "z" flag in our printf calls, and use it where appropriate. Since C99, it's been standard for printf and friends to accept a "z" size modifier, meaning "whatever size size_t has". Up to now we've generally dealt with printing size_t values by explicitly casting them to unsigned long and using the "l" modifier; but this is really the wrong thing on platforms where pointers are wider than longs (such as Win64). So let's start using "z" instead. To ensure we can do that on all platforms, teach src/port/snprintf.c to understand "z", and add a configure test to force use of that implementation when the platform's version doesn't handle "z". Having done that, modify a bunch of places that were using the unsigned-long hack to use "z" instead. This patch doesn't pretend to have gotten everyplace that could benefit, but it catches many of them. I made an effort in particular to ensure that all uses of the same error message text were updated together, so as not to increase the number of translatable strings. It's possible that this change will result in format-string warnings from pre-C99 compilers. We might have to reconsider if there are any popular compilers that will warn about this; but let's start by seeing what the buildfarm thinks. Andres Freund, with a little additional work by me

32-bit operating system, unless you have large file support enabled. By
default, we make the limit 1 GB to avoid any possible integer-overflow

a large relation into more chunks than necessary, so it seems best to err
in the direction of a small limit. A power-of-2 value is recommended to

Convert the arithmetic for shared memory size calculation from 'int' to 'Size' (that is, size_t), and install overflow detection checks in it.

Allow kerberos name and username case sensitivity to be specified from postgresql.conf. --------------------------------------------------------------------------- Here's an updated version of the patch, with the following changes: 1) No longer uses "service name" as "application version". It's instead hardcoded as "postgres". It could be argued that this part should be backpatched to 8.0, but it doesn't make a big difference until you can start changing it with GUC / connection parameters. This change only affects kerberos 5, not 4. 2) Now downcases kerberos usernames when the client is running on win32. 3) Adds guc option for "krb_caseins_users" to make the server ignore case mismatch which is required by some KDCs such as Active Directory. Off by default, per discussion with Tom. This change only affects kerberos 5, not 4. 4) Updated so it doesn't conflict with the rendevouz/bonjour patch already in ;-) Magnus Hagander

Break out OpenSSL-specific code to separate files. This refactoring is in preparation for adding support for other SSL implementations, with no user-visible effects. There are now two #defines, USE_OPENSSL which is defined when building with OpenSSL, and USE_SSL which is defined when building with any SSL implementation. Currently, OpenSSL is the only implementation so the two #defines go together, but USE_SSL is supposed to be used for implementation-independent code. The libpq SSL code is changed to use a custom BIO, which does all the raw I/O, like we've been doing in the backend for a long time. That makes it possible to use MSG_NOSIGNAL to block SIGPIPE when using SSL, which avoids a couple of syscall for each send(). Probably doesn't make much performance difference in practice - the SSL encryption is expensive enough to mask the effect - but it was a natural result of this refactoring. Based on a patch by Martijn van Oosterhout from 2006. Briefly reviewed by Alvaro Herrera, Andreas Karlsson, Jeff Janes.

Move substitute extern declarations to end of file, so that they are not read until after we've read the port-specific header file. In particular this should make it safer to #include system headers for inet_aton; in general it seems that the port header file ought to be in a position to set definitions before we do stuff based on having a definition or not.

Make Win32 build use our port/snprintf.c routines, instead of depending on libintl which may or may not provide what we need. Make a few marginal cleanups to ensure this works. Andrew Dunstan and Tom Lane.

Use Intel SSE 4.2 CRC instructions where available. Modern x86 and x86-64 processors with SSE 4.2 support have special instructions, crc32b and crc32q, for calculating CRC-32C. They greatly speed up CRC calculation. Whether the instructions can be used or not depends on the compiler and the target architecture. If generation of SSE 4.2 instructions is allowed for the target (-msse4.2 flag on gcc and clang), use them. If they are not allowed by default, but the compiler supports the -msse4.2 flag to enable them, compile just the CRC-32C function with -msse4.2 flag, and check at runtime whether the processor we're running on supports it. If it doesn't, fall back to the slicing-by-8 algorithm. (With the common defaults on current operating systems, the runtime-check variant is what you get in practice.) Abhijit Menon-Sen, heavily modified by me, reviewed by Andres Freund.

Support varlena fields with single-byte headers and unaligned storage. This commit breaks any code that assumes that the mere act of forming a tuple (without writing it to disk) does not "toast" any fields. While all available regression tests pass, I'm not totally sure that we've fixed every nook and cranny, especially in contrib. Greg Stark with some help from Tom Lane

Extend yesterday's patch making BLCKSZ and RELSEG_SIZE configurable to also let XLOG_BLCKSZ and XLOG_SEG_SIZE be set via configure. Per a proposal by Mark Wong, though I thought it better to call the switches after "wal" rather than "xlog".

Undo autoconf 2.69's attempt to #define _DARWIN_USE_64_BIT_INODE. Defining this symbol causes OS X 10.5 to use a buggy version of readdir(), which can sometimes fail with EINVAL if the previously-fetched directory entry has been deleted or renamed. In later OS X versions that bug has been repaired, but we still don't need the #define because it's on by default. So this is just an all-around bad idea, and we can do without it.
