This adds a 'MOVE' sub-command to ALTER TABLESPACE which allows moving sets of
objects from one tablespace to another. This can be extremely handy and avoids
a lot of error-prone scripting. ALTER TABLESPACE ... MOVE will only move
objects the user owns, will notify the user if no objects were found, and can
be used to move ALL objects or specific types of objects (TABLES, INDEXES, or
MATERIALIZED VIEWS).
Previously, lookups of non-existent user names could return "Success";
it will now return "User does not exist" by resetting errno. This also
centralizes the user name lookup code in libpgport.

When wal_level=logical, we'll log columns from the old tuple as
configured by the REPLICA IDENTITY facility added in commit
07cacba983. This makes it possible
a properly-configured logical replication solution to correctly
follow table updates even if they change the chosen key columns,
or, with REPLICA IDENTITY FULL, even if the table has no key at
all. Note that updates which do not modify the replica identity
column won't log anything extra, making the choice of a good key
(i.e. one that will rarely be changed) important to performance
when wal_level=logical is configured.
Each insert, update, or delete to a catalog table will also log
the CMIN and/or CMAX values of stamped by the current transaction.
This is necessary because logical decoding will require access to
historical snapshots of the catalog in order to decode some data
types, and the CMIN/CMAX values that we may need in order to judge
row visibility may have been overwritten by the time we need them.

Many committers seem to now be using a work flow in which back-patched
commits are timestamped minutes or even hours apart in different branches
(most likely because they commit in one branch before starting work on
the next one). git_changelog was failing to merge its reports in such
cases, so increase the max time it's willing to merge commits across.
I considered getting rid of the limit altogether, but that produces
some odd results in terms of how the merged commit gets sorted relative
to unrelated commits.
The C and POSIX standards state that strncpy's behavior is undefined when
source and destination areas overlap. While it remains dubious whether any
implementations really misbehave when the pointers are exactly equal, some
platforms are now starting to force the issue by complaining when an
undefined call occurs. (In particular OS X 10.9 has been seen to dump core
here, though the exact set of circumstances needed to trigger that remain
elusive. Similar behavior can be expected to be optional on Linux and
other platforms in the near future.) So tweak the code to explicitly do
nothing when nothing need be done.
Back-patch to all active branches. In HEAD, this also lets us get rid of
an exception in valgrind.supp.
Per discussion of a report from Matthias Schmitt.
asprintf(), aside from not being particularly portable, has a fundamentally
badly-designed API; the psprintf() function that was added in passing in
the previous patch has a much better API choice. Moreover, the NetBSD
implementation that was borrowed for the previous patch doesn't work with
non-C99-compliant vsnprintf, which is something we still have to cope with
on some platforms; and it depends on va_copy which isn't all that portable
either. Get rid of that code in favor of an implementation similar to what
we've used for many years in stringinfo.c. Also, move it into libpgcommon
since it's not really libpgport material.
I think this patch will be enough to turn the buildfarm green again, but
there's still cosmetic work left to do, namely get rid of pg_asprintf()
in favor of using psprintf(). That will come in a followon patch.
Continuing 63f32f3416, libpgcommon should
depend on libpgport, but not vice versa. But wait_result_to_str() in
wait_error.c depends on pstrdup() in libpgcommon. So move exec.c and
wait_error.c from libpgport to libpgcommon. Also switch the link order
in the place that's actually used by the failing ecpg builds.
The function declarations have been left in port.h for now. That should
perhaps be separated sometime.
Commit 95ef6a3448 removed the
ability to create rules on an individual column as of 7.3, but
left some residual code which has since been useless. This cleans
up that dead code without any change in behavior other than
dropping the useless column from the catalog.

Valgrind "client requests" in aset.c and mcxt.c teach Valgrind and its
Memcheck tool about the PostgreSQL allocator. This makes Valgrind
roughly as sensitive to memory errors involving palloc chunks as it is
to memory errors involving malloc chunks. Further client requests in
PageAddItem() and printtup() verify that all bits being added to a
buffer page or furnished to an output function are predictably-defined.
Those tests catch failures of C-language functions to fully initialize
the bits of a Datum, which in turn stymie optimizations that rely on
_equalConst(). Define the USE_VALGRIND symbol in pg_config_manual.h to
enable these additions. An included "suppression file" silences nominal

New infrastructure is added which creates a set number of workers

handed out to these workers by the master process as needed.
pg_restore is adjusted to use this new infrastructure in place of the
old setup which created a new worker for each step on the fly. Parallel

available.
The parallel option is selected by the -j / --jobs command line

This appears to cause some intermittent file system problems
on Windows 8. Instead, set up the old data directory in its
intended final location to start with.
I had thought we weren't using this version of pqsignal() at all on
Windows, but that's wrong --- initdb is using it (and coping with the
POSIX-ish semantics of bare signal() :-(). So allow the file to be
built in WIN32+FRONTEND case, and add it to the MSVC build logic.
The previous commit didn't work on MSVC editions earlier than
Visual Studio 2011, apparently. This works by copying files into the
contrib directory, and making provision to clean them up, which should
work on all editions.
This enables non-backend code, such as pg_xlogdump, to use it easily.
The previous location, in src/backend/catalog/catalog.c, made that
essentially impossible because that file depends on many backend-only
facilities; so this needs to live separately.
The previous order of steps didn't literally work, because git clean
-fdx would delete the downloaded typedefs.list. Also, pgindent needs to
be called with a path when one is in at the top of the build tree.
libpgcommon is a new static library to allow sharing code among the
various frontend programs and backend; this lets us eliminate duplicate
implementations of common routines. We avoid libpgport, because that's
intended as a place for porting issues; per discussion, it seems better
to keep them separate.
The first use case, and the only implemented by this patch, is pg_malloc
and friends, which many frontend programs were already using.
At the same time, we can use this to provide palloc emulation functions
for the frontend; this way, some palloc-using files in the backend can
also be used by the frontend cleanly. To do this, we change palloc() in
the backend to be a function instead of a macro on top of
MemoryContextAlloc(). This was previously believed to cause loss of
performance, but this implementation has been tweaked by Tom and Andres
so that on modern compilers it provides a slight improvement over the
previous one.
This lets us clean up some places that were already with
localized hacks.
Most of the pg_malloc/palloc changes in this patch were authored by
Andres Freund. Zoltán Böszörményi also independently provided a form of
that. libpgcommon infrastructure was authored by Álvaro.

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.
This makes the naming inside plpgsql consistent and distinguishes the
file from the backend's gram.y file. It will also allow easier
refactoring of the bison make rules later on.
This script is a bit slow, but still it only takes a fraction of the time
the bison run does, so the overhead doesn't seem intolerable. And we
definitely need some mechanical aid here, because people keep missing
the need to add new keywords to the appropriate keyword-list production.
While at it, I moved check_keywords.pl from src/tools into
src/backend/parser where it's actually used, and did some very minor
cleanup on the script.
This was removed in commit cd00406774,

as to why it sometimes fails and sometimes doesn't.
Original patch from Owais Khani, substantially reworked and
extended by Andrew Dunstan.
We seem to have a rough policy that our Perl scripts should work with
Perl 5.8, so make this one do so. Main change is to not use the newfangled
\h character class in regexes; "[ \t]" is a serviceable replacement.
This includes fixing the MSVC copy of ecpg/preproc's version info, which
seems to have been overlooked repeatedly. Can't we fix that so there are
not two copies??
The header file is needed by any module that wants to use the PL/pgSQL
instrumentation plugin interface. Most notably, the pldebugger plugin needs
this. With this patch, it can be built using pgxs, without having the full
server source tree available.
This makes it much more convenient to build tools for Postgres that are
separately compiled and require a matching CRC implementation.
To prevent multiple copies of the CRC polynomial tables being introduced
into the postgres binaries, they are now included in the static library
libpgport that is mainly meant for replacement system functions. That
seems like a bit of a kludge, but there's no better place.
This cleans up building of the tools pg_controldata and pg_resetxlog,
which previously had to build their own copies of pg_crc.o.
In the future, external programs that need access to the CRC tables can
include the tables directly from the new header file pg_crc_tables.h.

Per recent work by Peter Geoghegan, it's significantly faster to
tuplesort on a single sortkey if ApplySortComparator is inlined into
quicksort rather reached via a function pointer. It's also faster
in general to have a version of quicksort which is specialized for
sorting SortTuple objects rather than objects of arbitrary size and
type. This requires a couple of additional copies of the quicksort
logic, which in this patch are generate using a Perl script. There
might be some benefit in adding further specializations here too,
but thus far it's not clear that those gains are worth their weight
in code footprint.
This fixes a longstanding but up to now benign bug in the way pg_dumpall

Backpatch to 9.1 where it applies cleanly. A simple workaround is available for earlier

We should generally use left-recursion not right-recursion to parse lists.
Bison hasn't got any built-in way to check for this type of inefficiency,
and I didn't find anything on the net in a quick search, so I wrote a
little Perl script to do it. Add to src/tools/ so we don't have to
re-invent this wheel next time we wonder if we're doing anything stupid.
Currently, the only place that seems to need fixing is plpgsql's stmt_else
production, so the problem doesn't appear to be common enough to warrant
trying to include such a test in our standard build process. If we did
want to do that, we'd need a way to ignore some false positives, such as
a_expr := '-' a_expr
Add option for parallel streaming of the transaction log while a
base backup is running, to get the logfiles before the server has
removed them.
Also add a tool called pg_receivexlog, which streams the transaction
log into files, creating a log archive without having to wait for
segments to complete, thus decreasing the window of data loss without
having to waste space using archive_timeout. This works best in
combination with archive_command - suggested usage docs etc coming later.
Use the CommitDate not the AuthorDate, as the former is representative of
the order in which things went into the main repository, and the latter
isn't very; we now have instances where the AuthorDate is as much as a
month before the patch really went in. Also, get rid of the "commit order
inversions" heuristic, which turns out not to do anything very desirable.
Instead we just print commits in strict timestamp order, interpreting the
"timestamp" of a merged commit as its timestamp on the newest branch it

whether the MSVC build scripts need work (likely they do).

Until now, our Serializable mode has in fact been what's called Snapshot
Isolation, which allows some anomalies that could not occur in any
serialized ordering of the transactions. This patch fixes that using a
method called Serializable Snapshot Isolation, based on research papers by
Michael J. Cahill (see README-SSI for full references). In Serializable
Snapshot Isolation, transactions run like they do in Snapshot Isolation,
but a predicate lock manager observes the reads and writes performed and
aborts transactions if it detects that an anomaly might occur. This method
produces some false positives, ie. it sometimes aborts transactions even
though there is no anomaly.
To track reads we implement predicate locking, see storage/lmgr/predicate.c.
Whenever a tuple is read, a predicate lock is acquired on the tuple. Shared
memory is finite, so when a transaction takes many tuple-level locks on a
page, the locks are promoted to a single page-level lock, and further to a
single relation level lock if necessary. To lock key values with no matching
tuple, a sequential scan always takes a relation-level lock, and an index
scan acquires a page-level lock that covers the search key, whether or not
there are any matching keys at the moment.
A predicate lock doesn't conflict with any regular locks or with another
predicate locks in the normal sense. They're only used by the predicate lock
manager to detect the danger of anomalies. Only serializable transactions
participate in predicate locking, so there should be no extra overhead for
for other transactions.
Predicate locks can't be released at commit, but must be remembered until
all the transactions that overlapped with it have completed. That means that
we need to remember an unbounded amount of predicate locks, so we apply a
lossy but conservative method of tracking locks for committed transactions.
If we run short of shared memory, we overflow to a new "pg_serial" SLRU
pool.
We don't currently allow Serializable transactions in Hot Standby mode.
That would be hard, because even read-only transactions can cause anomalies
that wouldn't otherwise occur.
Serializable isolation mode now means the new fully serializable level.
Repeatable Read gives you the old Snapshot Isolation level that we have
always had.

1. Resurrect the behavior where old commits on master will have Branch:
labels for branches sprouted after the commit was made. I'm still
dubious about this mode, but if you want it, say --post-date or -p.
2. Annotate the Branch: labels with the release or branch in which the
commit was publicly released. For example, on a release branch you could
see
Branch: REL8_3_STABLE Release: REL8_3_2 [92c3a8004] 2008-03-29 00:15:37 +0000
showing that the fix was released in 8.3.2. Commits on master will
usually instead have notes like
Branch: master Release: REL8_4_BR [6fc9d4272] 2008-03-29 00:15:28 +0000
showing that this commit is ancestral to release branches 8.4 and later.
If no Release: marker appears, the commit hasn't yet made it into any
release.
3. Add support for release branches older than 7.4.
4. The implementation is improved by running git log on each branch only
back to where the branch sprouts from master. This saves a good deal
of time (about 50% of the runtime when generating the complete history).
We generate the post-date-mode tags via a direct understanding that
they should be applied to master commits made before the branch sprouted,
rather than backing into them via matching (which isn't any too
reliable when people used identical log messages for successive commits).
1. Don't assume there's only one candidate match; check them all and use the
one with the closest timestamp. Avoids funny output when someone makes
several successive commits with the same log message, as certain people
have been known to do.
2. When the same commit (with the same SHA1) is reachable from multiple
branch tips, don't report it for all the branches; instead report it only
for the first such branch. Given our development practices, this case
arises only for commits that occurred before a given branch split off from
master. The original coding blamed old commits on *all* the branches,
which isn't terribly useful; the new coding blames such a commit only on
master.
1. Don't forget the last (oldest) commit on the oldest branch.
2. When considering which commit to print next, if two alternatives have
the same "distortion" score (which is actually the normal case, since
generally the "distortion" is 0), then choose the later timestamp to
print first. I don't know where Robert got the idea to ignore timestamps
and sort by branch age, but it wasn't a good idea: the resulting ordering
of commits was just plain bizarre anywhere that some branches had many
fewer commits than others, which is the typical situation for us.
Avoid depending on Date::Calc, which isn't in a basic Perl installation,
when we can equally well use Time::Local which is. Also fix the parsing
of timestamps to take heed of the timezone. (It looks like cvs2git emitted
all commit timestamps with zone GMT, so this refinement might've looked
unnecessary when looking at converted data; but it's needed now.)
Fix parsing of message bodies so that blank lines that may or may not get
emitted by "git log" aren't confused with real data. This avoids strange

wait until it is set. Latches can be used to reliably wait until a signal
arrives, which is hard otherwise because signals don't interrupt select()

On Unix, latches use the so called self-pipe trick under the covers to
implement the sleep until the latch is set, without race conditions. On
Windows, Windows events are used.
Use the new latch abstraction to sleep in walsender, so that as soon as
a transaction finishes, walsender is woken up to immediately send the WAL

is good.
