      Change planner to use the current true disk file size as its estimate of · 5374d097
      Tom Lane authored
      a relation's number of blocks, rather than the possibly-obsolete value
      in pg_class.relpages.  Scale the value in pg_class.reltuples correspondingly
      to arrive at a hopefully more accurate number of rows.  When pg_class
      contains 0/0, estimate a tuple width from the column datatypes and divide
      that into current file size to estimate number of rows.  This improved
      methodology allows us to jettison the ancient hacks that put bogus default
      values into pg_class when a table is first created.  Also, per a suggestion
      from Simon, make VACUUM (but not VACUUM FULL or ANALYZE) adjust the value
      it puts into pg_class.reltuples to try to represent the mean tuple density
      instead of the minimal density that actually prevails just after VACUUM.
      These changes alter the plans selected for certain regression tests, so
      update the expected files accordingly.  (I removed join_1.out because
      it's not clear if it still applies; we can add back any variant versions
      as they are shown to be needed.)

      Fix plperl and pltcl error handling per my previous proposal. SPI · 35f49941
      Tom Lane authored
      operations are now run as subtransactions, so that errors in them
      can be reported as ordinary Perl or Tcl errors and caught by the
      normal error handling convention of those languages.  Also do some
      minor code cleanup in pltcl.c: extract a large chunk of duplicated
      code in pltcl_SPI_execute and pltcl_SPI_execute_plan into a shared
      subroutine.

      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.
