format codes are misapplied to a numeric argument. (The code still produces
a pretty bogus error message in such cases, but I'll settle for stopping the
crash for now.) Per bug #4700 from Sergey Burladyan.
Problem exists in all supported branches, so patch all the way back.
In HEAD, also clean up some ugly coding in the nearby cache management
code.

some bufmgr probes, take out redundant and memory-leak-inducing path arguments
to smgr__md__read__done and smgr__md__write__done, fix bogus attempt to
recalculate space used in sort__done, clean up formatting in places where
I'm not sure pgindent will do a nice job by itself.

So, treat them as part of word.

running pg_restore, which might run in parallel).
Only reopen archive file when we really need to read from it, in parallel code. Otherwise,
close it immediately in a worker, if possible.

exact-match pattern (no wildcard) can be index-optimized in some cases where a
prefix-match pattern cannot; specifically, since the required index clause is
simple equality, it works for regular text/varchar indexes even when the
locale is not C. I'm not sure how often this case really comes up, but since
it requires hardly any additional work to handle it, we might as well get it
right. Motivated by a discussion on the JDBC list.

for consistency with the (relatively) recent addition of typmod to SubLink.
An example of why it's a good idea is to be seen in the recent "failed to
locate grouping columns" bug, which wouldn't have happened if a SubPlan
exposed the same typmod info as the SubLink it was derived from.
This could be back-patched, since it doesn't affect any on-disk data format,
but for the moment it doesn't seem necessary to do so.

by the planning process. This prevents the "failed to locate grouping columns"
error recently reported by Dickson Guedes. That happens because planning
replaces SubLinks by SubPlans in the subquery's targetlist, and exprTypmod()
is smarter about the former than the latter, causing the apparent type of
the subquery's output columns to change. This seems to be a deficiency we
should fix in exprTypmod(), but that will be a much more invasive patch
with possible side-effects elsewhere, so I'll do that only in HEAD.
Back-patch to 8.3. Arguably the lack of a copying step is broken/dangerous
all the way back, but in the absence of known problems I'll refrain from
making the older branches pay the extra cost. (The reason this particular
symptom didn't appear before is that exprTypmod() wasn't smart about SubLinks
either, until 8.3.)

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.

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.

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.

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.

- 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.

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.

it saves something. And this is used enough to be a hotspot.

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

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.

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.
