Update FSM on WAL replay. This is a bit limited; the FSM is only updated

updates, though). The 20% cutoff should avoid most of the overhead, when

This is mostly to avoid the nasty worst case scenario, where you replay
from a PITR archive, and the FSM information in the base backup is really
out of date. If there was a lot of pages that the outdated FSM claims to
have free space, but don't actually have any, the first unlucky inserter

though I had to add some missing translations to the older branches in
order to expose the failure in the particular test case I was using.

Add support for multiple error messages from libpq, by simply appending them
after each other (since we already add a newline on each, this makes them
multiline).
Previously a new error would just overwrite the old one, so for example any
error caused when trying to connect with SSL enabled would be overwritten
by the error message form the non-SSL connection when using sslmode=prefer.

Better solution to the IN-list issue: instead of having an arbitrary cutoff,
treat Var and non-Var IN-list items differently. Only non-Var items are
candidates to go into an ANY(ARRAY) construct --- we put all Vars as separate
OR conditions on the grounds that that leaves more scope for optimization.
Per suggestion from Robert Haas.

Be a little smarter about qual handling for semi-joins: a qual that mentions
only the outer side can be pushed down rather than having to be evaluated
at the join.

Add a heuristic to transformAExprIn() to make it prefer expanding "x IN (list)"
into an OR of equality comparisons, rather than x = ANY(ARRAY[...]), when there
are Vars in the right-hand side. This avoids a performance regression compared
to pre-8.2 releases, in cases where the OR form can be optimized into scans
of multiple indexes. Limit the possible downside by preferring this form only
when the list isn't very long (I set the cutoff at 32 elements, which is a
bit arbitrary but in the right ballpark). Per discussion with Jim Nasby.
In passing, also make it try the OR form if it cannot select a common type
for the array elements; we've seen a complaint or two about how the OR form
worked for such cases and ARRAY doesn't.
