previously repointed TABLE dependencies to TABLE DATA.  Mea culpa.

make it include the time for the possible smgropen() call, but that
results in a null pointer dereference :-(.

An alternative solution would be to fetch the buffer tag instead of
looking at *reln, but I'll just put it back as it was for the moment.

BTW, this indicates that DTrace probes evaluate their arguments even
when nominally inactive.  What was that about "zero cost", again?

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.
