Make pg_reload_conf(), pg_rotate_logfile(), and pg_cancel_backend()
return a boolean rather than an integer to indicate success or failure.
Along the way, make some minor cleanups to dbsize.c -- in particular,
use elog() rather than ereport() for "shouldn't happen" error
conditions, and remove some of the more flagrant violations of the
Postgres indentation conventions.
Catalog version bumped.
bytes. This shouldn't make any difference on x86 machines, where the size
happened to be 16 bytes anyway, but on 64-bit machines and machines with
slock_t int or wider, it will speed array indexing and hopefully reduce
SMP cache contention effects. Per recent experimentation.
the builtin functions (although some more entries are still needed),
and remove the duplicate index entries that have been causing
collateindex.pl warnings. Consistently use "int" and "bigint", rather
than a mix of "int", "integer", "int4", "bigint", and "int8". Make
parenthesis style in syntax examples more consistent. Various
copy-editing for newly-added documentation and SGML markup fixes.
recovered. I did not see any actual leak while testing this in CVS tip,
but 8.0 definitely has a problem with leaking the space temporarily
palloc'd by BufferSync(). In any case this seems a good idea to forestall
similar problems in future. Per report from Arjen van der Meijden.

about when multicolumn indexes can be used. Also some minor editorial
work in other parts of the chapter.
to drop connections unceremoniously. Also some other marginal cleanups:
don't query getsockopt() repeatedly if it fails, and avoid having the
apparent definition of struct Port depend on which system headers you
might have included or not. Oliver Jowett and Tom Lane.
rather than "-" for the "dash" character. Correct SGML markup. Make
references to the names of contributors more consistent. Rewrite a bit
of prose, and make some other similar cleanups.
> found in a pg_dump archive. It had problems with dollar-quote tags
broken across bufferload boundaries (this may explain bug report from
Rod Taylor), also with dollar-quote literals of the form $a$a$...,
and was also confused about the rules for backslash in double quoted
identifiers (ie, they're not special). Also put in placeholder support
for E'...' literals --- this will need more work later.

resolve recent complaints that password prompting is broken in pg_restore
on Windows. Note that password prompting and reading from stdin is an
unworkable combination on Windows ... but that was true anyway.
is certainly no longer immutable, but must indeed be marked volatile.
I wonder if it should use the value of now() (that is, transaction
start time) so that it could be marked stable. But it's probably not
important enough to be worth changing the code for ... indeed, I'm not
even going to force an initdb for this catalog change, seeing that we
just did one a few hours ago.
in the zic database or zone names found in the date token table. This
preserves the old ability to do AT TIME ZONE 'PST' along with the new
ability to do AT TIME ZONE 'PST8PDT'. Per gripe from Bricklen Anderson.
Also, fix some inconsistencies in usage of TZ_STRLEN_MAX --- the old
code had the potential for one-byte buffer overruns, though given
alignment considerations it's unlikely there was any real risk.

originally proposed as a stopgap solution. For the moment, the initial
contents only include languages shipped with the core distribution.
as per my recent proposal. For now the template data is hard-wired in
proclang.c --- this should be replaced later by a new shared system
catalog, but we don't want to force initdb during 8.1 beta. This change
lets us cleanly load existing dump files even if they contain outright
wrong information about a PL's support functions, such as a wrong path
to the shared library or a missing validator function. Also, we can
revert the recent kluges to make pg_dump dump PL support functions that
are stored in pg_catalog.
While at it, I removed the code in pg_regress that replaced $libdir
with a hardcoded path for temporary installations. This is no longer
needed given our support for relocatable installations.
when there are extra resjunk columns in the child node. I found some
additional cases involving Append nodes that weren't handled by the
prior patch, and it's not clear how to fix them in the same way without
breaking inheritance cases. So the prudent path seems to be to narrow
the scope of the optimization.

SubqueryScan node just below the non-projecting node. For simplicity
I made it recopy always. Per bug report from Allan Wang and Michael Fuhr.
