RHS that can't be unique-ified --- join_is_legal has to check that before
deciding to build a join, else we'll have an unimplementable joinrel.

a mismatching installation. Pick a default port number calculated from the
version number, and try a few times with other numbers if that one doesn't
work. Check if we can connect to the port before starting our own postmaster,
to detect some other server already running there. To simplify the code,
drop --temp-port option and use --port for both temp-install and pre-installed
case.

DestReceiver created during postquel_start needs to be destroyed during
postquel_end. In a moment of brain fade I had assumed this would be taken
care of by FreeQueryDesc, but it's not (and shouldn't be).

results (ie, an empty "broken" buffer) if memory overrun occurs anywhere
along the way to filling the buffer. The previous coding would just silently
discard portions of the intended buffer contents, as exhibited in trouble
report from Sam Mason. Also, tweak psql's main loop to correctly detect
and report such overruns. There's probably much more that should be done
in this line, but this is a start.

by hand. As an added bonus, the new code is smaller and more understandable,
and the ugly loops are gone.
This had been discussed all along but never implemented. It became clear that
it really needed to be fixed after a bug report by Pavan Deolasee.

libpq. As noted by Peter, adding this variable created a risk of unexpected
connection failures when talking to older server versions, and since it
doesn't do anything you can't do with PGOPTIONS, it doesn't seem really
necessary. Removing it does occasion a few extra lines in pg_regress.c,
but saving a getenv() call per libpq connection attempt is perhaps worth
that anyway.

This uses the function fnmatch() which is not available on all platforms
(notably Windows), so import the implementation from NetBSD into src/port.

the bgwriter immediately. This covers the case where the bgwriter is still
starting up, as seen in a recent buildfarm failure. In future it might also
assist with clean recovery after a bgwriter termination and restart ---
right now the postmaster treats early bgwriter exit as a system crash,
but that might not always be so.

though it is an inner rather than outer join type. This essentially means
that we don't bother to separate "pushed down" qual conditions from actual
join quals at a semijoin plan node; which is okay because the restrictions of
SQL syntax make it impossible to have a pushed-down qual that references the
inner side of a semijoin. This allows noticeably better optimization of
IN/EXISTS cases than we had before, since the equivalence-class machinery can
now use those quals. Also fix a couple of other mistakes that had essentially
disabled the ability to unique-ify the inner relation and then join it to just
a subset of the left-hand relations. An example case using the regression
database is
select * from tenk1 a, tenk1 b
where (a.unique1,b.unique2) in (select unique1,unique2 from tenk1 c);
which is planned reasonably well by 8.3 and earlier but had been forcing a
cartesian join of a/b in CVS HEAD.

as LIKE. I oversimplified this code when removing support for plan-time
determination of index operator lossiness back in April --- I had thought
create_bitmap_subplan could stop returning two separate lists of qual
conditions, but it still must so that we can treat special operators
correctly in create_bitmap_scan_plan. Per report from Rushabh Lathia.
