      Use a hopefully-more-reliable method of detecting default selectivity · 547bb4a7
      Tom Lane authored
      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...

      Create 'default_tablespace' GUC variable that supplies a TABLESPACE · 98e8b480
      Tom Lane authored
      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.
