Peter Eisentraut 73c8596488 Allow running src/tools/msvc/mkvcbuild.pl under not Windows
This to allow verifying the MSVC build file generation without having
to have Windows.

To do this, we avoid Windows-specific Perl modules and don't run the
"cl" compiler or "nmake".  The resulting build files won't actually be
completely correct, but it's useful enough.

Peter Eisentraut 957338418b Require stdint.h
stdint.h belongs to the compiler (as opposed to inttypes.h), so by
requiring a C99 compiler we can also require stdint.h
unconditionally.  Remove configure checks and other workarounds for
it.

This also removes a few steps in the required portability adjustments
to the imported time zone code, which can be applied on the next
import.

When using GCC on a platform that is otherwise pre-C99, this will now
require at least GCC 4.5, which is the first release that supplied a
standard-conforming stdint.h if the native platform didn't have it.

Peter Eisentraut b691c189c6 Simplify passing of configure arguments to pg_config
The previous system had configure put the value into the makefiles and
then have the makefiles pass them to the build of pg_config.  That was
put in place when pg_config was a shell script.  We can simplify that
by having configure put the value into pg_config.h directly.  This
also makes the standard build system match how the MSVC build system
already does it.

Tom Lane c32704441d Add configure probe for rl_completion_suppress_quote.
I had supposed that all versions of Readline that have filename
quoting hooks also have the rl_completion_suppress_quote variable.
But it seems OpenBSD managed to find a version someplace that does
not, so we'll have to expend a separate configure probe for that.

make it necessary to frob that variable.  Hooray!)

Tom Lane cd69ec66c8 Improve psql's tab completion for filenames.
The Readline library contains a fair amount of knowledge about how to
tab-complete filenames, but it turns out that that doesn't work too well
unless we follow its expectation that we use its filename quoting hooks
to quote and de-quote filenames.  We were trying to do such quote handling
within complete_from_files(), and that's still what we have to do if we're
using libedit, which lacks those hooks.  But for Readline, it works a lot
better if we tell Readline that single-quote is a quoting character and
then provide hooks that know the details of the quoting rules for SQL
and psql meta-commands.

Hence, resurrect the quoting hook functions that existed in the original
version of tab-complete.c (and were disabled by commit f6689a328 because
they "didn't work so well yet"), and whack on them until they do seem to
work well.

Notably, this fixes bug #16059 from Steven Winfield, who pointed out
that the previous coding would strip quote marks from filenames in SQL
COPY commands, even though they're syntactically necessary there.
Now, we not only don't do that, but we'll add a quote mark when you
tab-complete, even if you didn't type one.

Getting this to work across a range of libedit versions (and, to a
lesser extent, libreadline versions) was depressingly difficult.
It will be interesting to see whether the new regression test cases
pass everywhere in the buildfarm.

Some future patch might try to handle quoted SQL identifiers with
similar explicit quoting/dequoting logic, but that's for another day.

Patch by me, reviewed by Peter Eisentraut.

Amit Kapila 40d964ec99 Allow vacuum command to process indexes in parallel.
This feature allows the vacuum to leverage multiple CPUs in order to
process indexes.  This enables us to perform index vacuuming and index
cleanup with background workers.  This adds a PARALLEL option to VACUUM
command where the user can specify the number of workers that can be used
to perform the command which is limited by the number of indexes on a
table.  Specifying zero as a number of workers will disable parallelism.
This option can't be used with the FULL option.

Each index is processed by at most one vacuum process.  Therefore parallel
vacuum can be used when the table has at least two indexes.

The parallel degree is either specified by the user or determined based on
the number of indexes that the table has, and further limited by
max_parallel_maintenance_workers.  The index can participate in parallel
vacuum iff it's size is greater than min_parallel_index_scan_size.

downloads all the relevant files and runs the generation script.

There is also a new script for generating the table of combining
characters for ucs_wcwidth().  That table is now in a separate include
file rather than hardcoded into the middle of other code.  This is
based on the script that was used for generating
d8594d123c, but the script itself wasn't

Peter Eisentraut 8f4fb4c648 Generate pg_config.h from pg_config.h.in on Windows
Previously, the Windows MSVC build generated pg_config.h from a
hard-coded pg_config.h.win32 with some ad hoc postprocessing.  The
pg_config.h.win32 file required manual maintenance and was as a result
frequently out of date.

Instead, have the MSVC build scripts emulate what configure and
config.status do: collect a list of defines and then create
pg_config.h from pg_config.h.in by changing the appropriate lines.

The previous setup was made to support old Windows build systems that
didn't have any text processing capabilities, but the current system
has Perl, so it's not a problem.  pg_config.h.win32 is removed.

In order to try to keep the Windows side of things more up to date in
the future, we now also require that all symbols found in
pg_config.h.in are defined in the MSVC build system.  So if there is a
change in configure that results in a new symbol, an update in
Solution.pm will be required.

The other headers managed by AC_CONFIG_HEADERS in configure, namely
src/include/pg_config_ext.h and
src/interfaces/ecpg/include/ecpg_config.h, get the same treatment, so
this removes even more ad hoc code in the MSVC build scripts.

Michael Paquier e1551f96e6 Refactor attribute mappings used in logical tuple conversion
Tuple conversion support in tupconvert.c is able to convert rowtypes
between two relations, inner and outer, which are logically equivalent
but have a different ordering or even dropped columns (used mainly for
inheritance tree and partitions).  This makes use of attribute mappings,
which are simple arrays made of AttrNumber elements with a length
matching the number of attributes of the outer relation.  The length of
the attribute mapping has been treated as completely independent of the
mapping itself until now, making it easy to pass down an incorrect
mapping length.

This commit refactors the code related to attribute mappings and moves
it into an independent facility called attmap.c, extracted from
tupconvert.c.  This merges the attribute mapping with its length,
avoiding to try to guess what is the length of a mapping to use as this
is computed once, when the map is built.

This will avoid mistakes like what has been fixed in dc816e58, which has
used an incorrect mapping length by matching it with the number of
attributes of an inner relation (a child partition) instead of an outer
relation (a partitioned table).

Peter Eisentraut f14413b684 Sort out getpeereid() and peer auth handling on Windows

of Unix-domain socket support on Windows, that needs to be handled

Windows doesn't support getpeereid() at this time, so we use the

of picking up the replacement from libpgport, instead of the custom
overrides that it was doing before.

But then Windows doesn't have struct passwd, so this patch sprinkles

float4 is now always pass-by-value; the pass-by-reference code path is
completely removed.

Tom Lane 7a0574b50e Fix ecpglib.h to declare bool consistently with c.h.
This completes the task begun in commit 1408d5d86, to synchronize
ECPG's exported definitions with the definition of bool used by
c.h (and, therefore, the one actually in use in the ECPG library).
On practically all modern platforms, ecpglib.h will now just
include <stdbool.h>, which should surprise nobody anymore.
That removes a header-inclusion-order hazard for ECPG clients,
who previously might get build failures or unexpected behavior
depending on whether they'd included <stdbool.h> themselves,
and if so, whether before or after ecpglib.h.

On platforms where sizeof(_Bool) is not 1 (only old PPC-based
Mac systems, as far as I know), things are still messy, as
inclusion of <stdbool.h> could still break ECPG client code.
There doesn't seem to be any clean fix for that, and given the
probably-negligible population of users who would care anymore,
it's not clear we should go far out of our way to cope with it.
This change at least fixes some header-inclusion-order hazards
for our own code, since c.h and ecpglib.h previously disagreed
on whether bool should be char or unsigned char.

To implement this with minimal invasion of ECPG client namespace,
move the choice of whether to rely on <stdbool.h> into configure,
and have it export a configuration symbol PG_USE_STDBOOL.

ecpglib.h no longer exports definitions for TRUE and FALSE,
only their lowercase brethren.  We could undo that if we get
push-back about it.

Ideally we'd back-patch this as far as v11, which is where c.h
started to rely on <stdbool.h>.  But the odds of creating problems
for formerly-working ECPG client code seem about as large as the
odds of fixing any non-working cases, so we'll just do this in HEAD.

Andres Freund 26aaf97b68 Make StringInfo available to frontend code.
There's plenty places in frontend code that could benefit from a
string buffer implementation. Some because it yields simpler and
faster code, and some others because of the desire to share code
between backend and frontend.

While there is a string buffer implementation available to frontend
code, libpq's PQExpBuffer, it is clunkier than stringinfo, it
introduces a libpq dependency, doesn't allow for sharing between
frontend and backend code, and has a higher API/ABI stability
requirement due to being exposed via libpq.

Therefore it seems best to just making StringInfo being usable by
frontend code. There's not much to do for that, except for rewriting
two subsequent elog/ereport calls into others types of error
reporting, and deciding on a maximum string length.

For the maximum string size I decided to privately define MaxAllocSize
to the same value as used in the backend. It seems likely that we'll
want to reconsider this for both backend and frontend code in the not
too far away future.

For now I've left stringinfo.h in lib/, rather than common/, to reduce
the likelihood of unnecessary breakage. We could alternatively decide
to provide a redirecting stringinfo.h in lib/, or just not provide
compatibility.

Andres Freund 01368e5d9d Split all OBJS style lines in makefiles into one-line-per-entry style.
When maintaining or merging patches, one of the most common sources
for conflicts are the list of objects in makefiles. Especially when
the split across lines has been changed on both sides, which is
somewhat common due to attempting to stay below 80 columns, those
conflicts are unnecessarily laborious to resolve.

By splitting, and alphabetically sorting, OBJS style lines into one
object per line, conflicts should be less frequent, and easier to
resolve when they still occur.

Peter Eisentraut 38d8dce61f Remove some code for old unsupported versions of MSVC
As of d9dd406fe2, we require MSVC 2013,
which means _MSC_VER >= 1800.  This means that conditionals about
older versions of _MSC_VER can be removed or simplified.

Previous code was also in some cases handling MinGW, where _MSC_VER is
not defined at all, incorrectly, such as in pg_ctl.c and win32_port.h,
leading to some compiler warnings.  This should now be handled better.

Alexander Korotkov 6cae9d2c10 Improve handling of NULLs in KNN-GiST and KNN-SP-GiST
This commit improves subject in two ways:

 * It removes ugliness of 02f90879e7, which stores distance values and null
   flags in two separate arrays after GISTSearchItem struct.  Instead we pack
   both distance value and null flag in IndexOrderByDistance struct.  Alignment
   overhead should be negligible, because we typically deal with at most few
   "col op const" expressions in ORDER BY clause.
 * It fixes handling of "col op NULL" expression in KNN-SP-GiST.  Now, these
   expression are not passed to support functions, which can't deal with them.
   Instead, NULL result is implicitly assumed.  It future we may decide to
   teach support functions to deal with NULL arguments, but current solution is
   bugfix suitable for backpatch.

Depending on the system used, t/*.pl may not be expanded into a list of
tests which can be consumed by prove when attempting to run TAP tests on
a given path.  Fix that by using glob() directly in the script, to make
sure that a complete list of tests is provided.  This has not proved to
be an issue with MSVC as the list was properly expanded, but it is on
Linux with perl's system().

Tom Lane db43831899 Avoid using INFO elevel for what are fundamentally debug messages.
Commit 6f6b99d13 stuck an INFO message into the fast path for
checking partition constraints, for no very good reason except
that it made it easy for the regression tests to verify that
that path was taken.  Assorted later patches did likewise,
increasing the unsuppressable-chatter level from ALTER TABLE
even more.  This isn't good for the user experience, so let's
drop these messages down to DEBUG1 where they belong.  So as
not to have a loss of test coverage, create a TAP test that
runs the relevant queries with client_min_messages = DEBUG1
and greps for the expected messages.

This testing method is a bit brute-force --- in particular,
it duplicates the execution of a fair amount of the core
create_table and alter_table tests.  We experimented with
other solutions, but running any significant amount of
standard testing with client_min_messages = DEBUG1 seems
to have a lot of output-stability pitfalls, cf commits
bbb96c370 and 5655565c0.  Possibly at some point we'll look
into whether we can reduce the amount of test duplication.

Backpatch into v12, because some of these messages are new
in v12 and we don't really want to ship it that way.
