already changed initdb in a way that assumed it worked like this, seems
we'd better make it work like this.

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.
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.
particular the addition of bitmap scans and the relaxation of rules
about when multicolumn indexes can be used. Also some minor editorial
work in other parts of the chapter.
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.
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.
for procedural languages. This replaces the hard-wired table I had
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.
