* Allow database recovery where tablespaces can't be created

  When a pg_dump is restored, all tablespaces will attempt to be created
  in their original locations. If this fails, the user must be able to
  adjust the restore process.

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.

RestrictInfo nodes in the query expression.  Per example from James Robinson.

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.

- add some additional files to the dbmirror install (approved by
ssinger)

- add a makefile for contrib/mysql, and add mysql to the list of
contribs build by default

- use xml2-config to pickup -I flags for libxml2 in contrib/xml and
contrib/xml2

Add the script name to the tmp directory name.

Move trap up now that the dir is more unique.

to DAY precision or coarser; leave the timezone alone when precision is
HOUR or less.  This avoids surprises for inputs near a DST transition
time, as per example from Matthew Gabeler-Lee.  (The only reason we
recalculate at all is so that outputs that are supposed to represent
days will come out as local midnight, and that's not relevant for sub-day
precision.)

use it, as per my proposal of yesterday.  This gives us a means of
determining the zone offset to impute to an unlabeled timestamp that
is both efficient and reliable, unlike all our previous tries involving
mktime() and localtime().  The behavior for invalid or ambiguous times
at a DST transition is fixed to be really and truly "assume standard
time", fixing a bug that has come and gone repeatedly but was back
again in 7.4.  (There is some ongoing discussion about whether we should
raise an error instead, but for the moment I'll make it do what it was
previously intended to do.)
