to process all inclusion switches then all exclusion switches, so that the
behavior is independent of switch ordering.
Use of -T does not cause non-table objects to be suppressed.  And
the patterns are now interpreted the same way psql's \d commands do it,
rather than as pure regex commands; this allows for example -t schema.tab
to do what it should have been doing all along.  Re-enable the --blobs
switch to do something useful, ie, add back blobs into a dump they were
otherwise suppressed from.

commands (and soon by pg_dump).

pg_dump as well as psql.  Since psql already uses dumputils.c, while there's
not any code sharing in the other direction, this seems the easiest way.
Also, fix misinterpretation of patterns using regex | by adding parentheses
(same bug found previously in similar_escape()).  This should be backpatched.

Apple developer tools.  We now use dlopen directly if available, and fall
back to the older code if not.  Chris Campbell

specify it explicitly in backend/Makefile.  Arrange for this value to
be known by get_stack_depth_rlimit() too.  Per suggestion from Magnus.

per suggestion from Peter.  Without this, the main doc links prevent
those files from being built.

quote chars inside quote marks, should emit one quote *and stay in inquotes

poor documentation of the feature ...

portable long options.  But we have had portable long options for a long
time now, so this is obsolete.  Now people have added options which *only*
work with -X but not as regular long option, so I'm putting a stop to this:
-X is deprecated; it still works, but it has been removed from the
documentation, and please don't add more of them.

query_list into the Portal, ie, the one seen and possibly modified by
the planner.  My fault :-(  Per report from Sergey Koposov.

max_stack_depth is not set to an unsafe value.

This commit also provides configure-time checking for <sys/resource.h>,
and cleans up some perhaps-unportable code associated with use of that
include file and getrlimit().

Also, tweak the code to work properly if someone sets max_stack_depth
to more than 2Gb, which guc.c will allow on a 64-bit machine.

overlapping possible matches for the separator string, such as
string_to_array('123xx456xxx789', 'xx').
Also, revise the logic of replace(), split_part(), and string_to_array()
to avoid O(N^2) work from redundant searches and conversions to pg_wchar
format when there are N matches to the separator string.
Backpatched the full patch as far as 8.0.  7.4 also has the bug, but the
code has diverged a lot, so I just went for a quick-and-dirty fix of the
bug itself in that branch.

win32.mak got patched for this, but not bcc32.mak.

been initialized yet.  This can happen because there are code paths that call
SysCacheGetAttr() on a tuple originally fetched from a different syscache
(hopefully on the same catalog) than the one specified in the call.  It
doesn't seem useful or robust to try to prevent that from happening, so just
improve the function to cope instead.  Per bug#2678 from Jeff Trout.  The
specific example shown by Jeff is new in 8.1, but to be on the safe side
I'm backpatching 8.0 as well.  We could patch 7.x similarly but I think
that's probably overkill, given the lack of evidence of old bugs of this ilk.

remaining functions, simplify pglz_compress's API to not require a useless
data copy when compression fails.  Also add a check in pglz_decompress that
the expected amount of data was decompressed.

and in particular offers a much cleaner workaround for the Intel compiler
bug that was affecting ginutil.c.

proposed patches from John Jorgensen and Steve Singer.

Buildfarm results from 'gazelle' show that there are indeed libedit
versions for which history.h is a needed header, even though it's
apparently been dropped entirely in other versions.  Grumble.

Per Bob Friesenhahn's report, this file is not supplied by some versions
of libedit, and even when it is supplied it seems to be just a link to
readline.h, so we don't need to include it anyway.
Also, ensure that we won't try to use a too-old version of Bison.
The previous coding would bleat but then use it anyway; better to invoke
the 'missing' script if any grammar files need to be rebuilt.
