1b3e769682 This patch makes some cleanups to contrib/ to silence some sparse
warnings:

- remove pointless "extern" keyword from some function definitions in
contrib/tsearch2

- use "NULL" not "0" as NULL pointer in contrib/tsearch,
contrib/tsearch2, contrib/pgbench, and contrib/vacuumlo

547bb4a7f2 Use a hopefully-more-reliable method of detecting default selectivity
estimates when combining the estimates for a range query.  As pointed out
by Miquel van Smoorenburg, the existing check for an impossible combined
result would quite possibly fail to detect one default and one non-default
input.  It seems better to use the default range query estimate in such
cases.  To do so, add a check for an estimate of exactly DEFAULT_INEQ_SEL.
This is a bit ugly because it introduces additional coupling between
clauselist_selectivity and scalarltsel/scalargtsel, but it's not like
there wasn't plenty already...

3a372d61d0 Kris Jurka pointed out that the qualified_name production wasn't
working as intended --- for some reason, FROM a.b.c was getting
parsed as if it were a function name and not a qualified name.
I think there must be a bug in bison, because it should have
complained that the grammar was ambiguous.  Anyway, fix it along
the same lines previously used for func_name vs columnref, and get
rid of the right-recursion in attrs that seems to have confused
bison.

336969e490 Add code to find_my_exec() to resolve a symbolic link down to the
actual executable location.  This allows people to continue to use
setups where, eg, postmaster is symlinked from a convenient place.

* Allow database recovery where tablespaces can't be created

  adjust the restore process.

4867afef7a Code cleanup in path.c and exec.c. Handle Windows drive and network specs
everywhere not just some places, get rid of . and .. when joining path
sections together.  This should eliminate most of the ugly paths like
/foo/bar/./baz that we've been generating.

3d6e538edf pred_test() logic was being too narrow-minded about where it might find

98e8b48053 Create 'default_tablespace' GUC variable that supplies a TABLESPACE
clause implicitly whenever one is not given explicitly.  Remove concept
of a schema having an associated tablespace, and simplify the rules for
selecting a default tablespace for a table or index.  It's now just
(a) explicit TABLESPACE clause; (b) default_tablespace if that's not an
empty string; (c) database's default.  This will allow pg_dump to use
SET commands instead of tablespace clauses to determine object locations
(but I didn't actually make it do so).  All per recent discussions.
