e43fd89762 Revert pg_bind_textdomain_codeset to a existant-but-empty function when
ENABLE_NLS is not defined, for better compatibility of the backend with
modules compiled the other way.

Per note from Tom after my previous commit.

328d235571 Separate the key word list that lived in keywords.c into a new header file
kwlist.h, to avoid having to link the backend object file into other programs
like pg_dump.  We can now simply symlink a single source file from the backend
(kwlookup.c, containing the shared routine ScanKeywordLookup) and compile it
locally, which is a lot cleaner.

00ce73778b Teach the planner to support index access methods that only implement
amgettuple or only implement amgetbitmap, instead of the former assumption
that every AM supports both APIs.  Extracted with minor editorialization
from Teodor's fast-GIN-insert patch; whatever becomes of that, this seems
like a simple and reasonable generalization of the index AM interface spec.

08eb37da4c Fix column privilege checking for cases where parent and child have different
attribute numbering.  Also, a parent whole-row reference should not require
select privilege on child columns that aren't inherited from the parent.

59156ad1b2 Put back our old workaround for machines that declare cbrt() in math.h but
fail to provide the function itself.  Not sure how we escaped testing anything
later than 7.3 on such cases, but they still exist, as per André Volpato's
report about AIX 5.3.

820984ba05 Clarify to the translator that yyerror() deals with the translation of
"syntax error", not the literal string.  I was previously confused on this
matter, but I have now verified that everything is translated properly.

45a10b2531 Add some sanity checks to CREATE CAST ... WITHOUT FUNCTION. Disallow

9add9f95c3 Don't actively violate the system limit of maximum open files (RLIMIT_NOFILE).
This avoids irritating kernel logs (if system overstep violations are enabled)
and also the grsecurity alert when starting PostgreSQL.

d657843a9a Remove the placeholder LWLockId in place of the removed FreeSpaceLock.
As pointed out by ITAGAKI Takahiro, we split SInvalLock into two in 8.4,
so to keep the numbers of the rest of the locks unchanged from 8.3, we
don't need a placeholder.

fd9e2accef When we are in error recursion trouble, arrange to suppress translation and
encoding conversion of any elog/ereport message being sent to the frontend.
This generalizes a patch that I put in last October, which suppressed
translation of only specific messages known to be associated with recursive
can't-translate-the-message behavior.  As shown in bug #4680, we need a more
general answer in order to have some hope of coping with broken encoding
conversion setups.  This approach seems a good deal less klugy anyway.

Patch in all supported branches.

32032d42b5 Fix usage of char2wchar/wchar2char. Changes:
- pg_wchar and wchar_t could have different size, so char2wchar
  doesn't call pg_mb2wchar_with_len to prevent out-of-bound
  memory bug
- make char2wchar/wchar2char symmetric, now they should not be
  called with C-locale because mbstowcs/wcstombs oftenly doesn't
  work correct with C-locale.
- Text parser uses pg_mb2wchar_with_len directly in case of
  C-locale and multibyte encoding

Per bug report by Hiroshi Inoue <inoue@tpf.co.jp> and
following discussion.

Backpatch up to 8.2 when multybyte support was implemented in tsearch.

876b37d50a Fix buffer allocations in encoding conversion routines so that they won't
fail on zero-length inputs.  This isn't an issue in normal use because the
conversion infrastructure skips calling the converters for empty strings.
However a problem was created by yesterday's patch to check whether the
right conversion function is supplied in CREATE CONVERSION.  The most
future-proof fix seems to be to make the converters safe for this corner case.

21eb6aeb36 Shave a few cycles in compare_pathkeys() by checking for pointer-identical
input lists before we grovel through the lists.  This doesn't save much,
but testing shows that the case of both inputs NIL is common enough that
it saves something.  And this is used enough to be a hotspot.

640796ff41 Reduce the maximum value of vacuum_cost_delay and autovacuum_vacuum_cost_delay
to 100ms (from 1000).  This still seems to be comfortably larger than the
useful range of the parameter, and it should help discourage people from
picking uselessly large values.  Tweak the documentation to recommend small
values, too.  Per discussion of a couple weeks ago.

07b9936a0f Temporarily (I hope) disable flattening of IN/EXISTS sublinks that are within
the ON clause of an outer join.  Doing so is semantically correct but results
in de-optimizing queries that were structured to take advantage of the sublink
style of execution, as seen in recent complaint from Kevin Grittner.  Since
the user can get the other behavior by reorganizing his query, having the
flattening happen automatically is just a convenience, and that doesn't
justify breaking existing applications.  Eventually it would be nice to
re-enable this, but that seems to require a significantly different approach
to outer joins in the executor.

5c4ca3b632 In CREATE CONVERSION, test that the given function is a valid conversion
function for the specified source and destination encodings. We do that by
calling the function with an empty string. If it can't perform the requested
conversion, it will throw an error.

Backport to 7.4 - 8.3. Per bug report #4680 by Denis Afonin.

f01313bc0d Improve create_unique_path to not be fooled by unrelated clauses that happen
to be syntactically part of a semijoin clause.  For example given
WHERE EXISTS(SELECT ... WHERE upper.var = lower.var AND some-condition)
where some-condition is just a restriction on the lower relation, we can
use unique-ification on lower.var after having applied some-condition within
the scan on lower.

f4fea44ce1 Remove outdated join_1.out regression test comparison file. This has
been broken for more than a month, so evidently it's not needed, at

eea49769d4 Fix an old problem in decompilation of CASE constructs: the ruleutils.c code
looks for a CaseTestExpr to figure out what the parser did, but it failed to
consider the possibility that an implicit coercion might be inserted above
the CaseTestExpr.  This could result in an Assert failure in some cases
(but correct results if Asserts weren't enabled), or an "unexpected CASE WHEN
clause" error in other cases.  Per report from Alan Li.

Back-patch to 8.1; problem doesn't exist before that because CASE was
implemented differently.

e549722a8b Get rid of the rather fuzzily defined FlattenedSubLink node type in favor of
making pull_up_sublinks() construct a full-blown JoinExpr tree representation
of IN/EXISTS SubLinks that it is able to convert to semi or anti joins.
This makes pull_up_sublinks() a shade more complex, but the gain in semantic
clarity is worth it.  I still have more to do in this area to address the
previously-discussed problems, but this commit in itself fixes at least one
bug in HEAD, as shown by added regression test case.

7babccb915 Add the possibility to specify an explicit validator function for foreign-data

the nearly empty libraries, and we are more free in how to implement the
