(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.

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...

The problem was the use of rint() to round, and then find the remainder,
causing the negative values.
for circle(polygon), which was missing; remove bogus entry for
point(lseg, lseg), which does not exist, and the documentation seemed to
describe lseg_interpt, which we already document as an operator not a
function. Also remove entry for box_intersect, which likewise is
preferentially used via the operator #.
is applied last, after other constraints such as name patterns. This
is useful first because the pg_foo_is_visible() functions are relatively
expensive, and second because it minimizes the prospects for race
conditions. The change is fragile though since it makes unwarranted
assumptions about planner behavior, ie, that WHERE clauses will be
executed in the original order if there's not reason to change it.
This should fix ... or at least hide ... an intermittent failure in the
prepared_xacts regression test, while we think about what else to do.
checked that the pointer is actually word-aligned. Casting a non-aligned
pointer to int32* is technically illegal per the C spec, and some recent
versions of gcc actually generate bad code for the memset() when given
such a pointer. Per report from Andrew Morrow.
