An attached patch is a small additional improvement.

This patch use appendStringInfoText instead of appendStringInfoString.
There is an overhead of PG_TEXT_GET_STR when appendStringInfoString is
executed by text type. This can be reduced by appendStringInfoText.

There's no tab-completion for "PREPARE TRANSACTION 'xxx'" since that
would be ambigous with "PREPARE xxx AS xx".

planning logic for bitmap indexscans.  Partial indexes create corner
cases in which a scan might be done with no explicit index qual conditions,
and the code wasn't handling those cases nicely.  Also be a little
tenser about eliminating redundant clauses in the generated plan.
Per report from Dmitry Karasik.

array "const" as well, but this would require multiple API changes and
does not seem to be worth the notational inconvenience.

An additional benefit is that changes in libpgport files correctly
propagate to force rebuild of the backend executable.  This is my
reworking of Rocco Altier's idea, and if it breaks anything it's
definitely my fault.

The first rule of portability for us is 'thou shalt have no other gods
before c.h', and a whole lot of these files were either not including
c.h at all, or including random system headers beforehand, either of
which sins can mess up largefile support nicely.  Once you have
included c.h, there is no need to re-include what it includes, either.

for such a role, membership in another role can be exploited only by doing
explicit SET ROLE.  The default inherit setting is TRUE, so by default
the behavior doesn't change, but creating a user with NOINHERIT gives closer
adherence to our current reading of SQL99.  Documentation still lacking,

roles --- pg_has_role() makes this a whole lot easier, removing the need
for most of the explicit joins with pg_user.  The views should be a tad
faster now, too.  Stephen Frost and Tom Lane.

I'm still working on the has_role function and information_schema changes.
