whether we seem to be running in a uniprocessor or multiprocessor.
The adjustment rules could probably still use further tweaking, but
I'm convinced this should be a win overall.

The pre-test has been shown to be a big loss on Opterons and at best a
wash on EM64T.

valid type information if they are asked to fetch the values part of a
pg_statistic slot; these arguments are unneeded if fetching only the
numbers part.  Use this to save a catcache lookup in btcostestimate,
which is looking like a bit of a hotspot in recent profiling.  Not a
big savings, but since it's essentially free, might as well do it.

A RestrictInfo representing an OR clause now contains two versions of
the contained expression, one with sub-RestrictInfos and one without.
clause_selectivity() should descend to the version with sub-RestrictInfos
so that it has a chance of caching its results for the OR's sub-clauses.
Failing to do so resulted in redundant planner effort.

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.

ie removing shared-dependency entries, should happen before non-rollbackable
ones.  That way a failure during the rollbackable part doesn't leave us
with inconsistent state.

traceable to grant options.  As per my earlier proposal, a GRANT made by
a role member has to be recorded as being granted by the role that actually
holds the grant option, and not the member.

like '23:59:60' because of fractional-second roundoff problems.  Trying
to control this upstream of the actual display code was hopeless; the right
way is to explicitly round fractional seconds in the display code and then
refigure the results if the fraction rounds up to 1.  Per bug #1927.

to call krb5_sname_to_principal() always.  Also, use krb_srvname rather
than the hardwired string 'postgres' as the appl_version string in the
krb5_sendauth/recvauth calls, to avoid breaking compatibility with PG
8.0.  Magnus Hagander

initialization.  Add spinlocking, fix EXEC_BACKEND unsafeness.

Per request from Marc Munro.

testing ownership if the caller isn't interested in any GOPTION bits
(which is the common case).  It did not matter in 8.0 where the ownership
test was just a trivial equality test, but it matters now.

level for unrecognized win32 error codes to LOG, and make messages
conform to style guide.  Per old suggestion from Qingqing Zhou, which
seems to have gotten lost in the shuffle.

Remove unportable use of tfind/tsearch in favor of bsearch.  Fix up
random number generator to use random() not rand() and to actually honor
its min/max arguments properly.  That wasn't so important before, but
with exposure of capability to ask for general ranges, it will be.
