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.
doesn't automatically inherit the privileges of roles it is a member of;
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,
and I think the information schema needs another look.
existing ones for object privileges. Update the information_schema for
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.
pg_strcasecmp and pg_strncasecmp ... but I see some of the former have
crept back in.
Eternal vigilance is the price of locale independence, apparently.

(This leaves only pgxs' MODULES case needing those rules.) Also,
compile pgsleep.c locally and add it to regress.so to avoid failure
on AIX.

Udpate documentation.
coding would ignore startup cost differences of less than 1% of the
estimated total cost; which was OK for normal planning but highly not OK
if a very small LIMIT was applied afterwards, so that startup cost becomes
the name of the game. Instead, compare startup and total costs fuzzily
but independently. This changes the plan selected for two queries in the
regression tests; adjust expected-output files for resulting changes in
row order. Per reports from Dawid Kuroczko and Sam Mason.
calculations for interval and time/timetz to behave sanely for both
integer and float timestamps; up to now I think it's been doing
something pretty strange...
