emit when given the --clean option, in favor of individual DROP ROLE
commands. The old technique could not possibly work in 8.1, and was
never a very good idea anyway IMHO. The DROP ROLE approach has the
defect that the DROPs will fail for roles that own objects or have
privileges, but perhaps we can improve that later.

generated by bitmap index scans. Along the way, simplify and speed up
the code for counting sequential and index scans; it was both confusing
and inefficient to be taking care of that in the per-tuple loops, IMHO.
initdb forced because of internal changes in pg_stat view definitions.
argument as a 'regclass' value instead of a text string. The frontend
conversion of text string to pg_class OID is now encapsulated as an
implicitly-invocable coercion from text to regclass. This provides
backwards compatibility to the old behavior when the sequence argument
is explicitly typed as 'text'. When the argument is just an unadorned
literal string, it will be taken as 'regclass', which means that the
stored representation will be an OID. This solves longstanding problems
with renaming sequences that are referenced in default expressions, as
well as new-in-8.1 problems with renaming such sequences' schemas or
moving them to another schema. All per recent discussion.
Along the way, fix some rather serious problems in dbmirror's support
for mirroring sequence operations (int4 vs int8 confusion for instance).
relocated after installation. We can't trust the installation paths
inserted into Makefile.global by configure, so instead we must get the
paths from pg_config. This requires extending pg_config to support all
the separately-configurable path names, but that was on TODO anyway.

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.

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.

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.
