Up to now, EXPLAIN has contented itself with printing the sort expressions in a Sort or Merge Append plan node. This patch improves that by annotating the sort keys with COLLATE, DESC, USING, and/or NULLS FIRST/LAST whenever nondefault sort ordering options are used. The output is now a reasonably close approximation of an ORDER BY clause equivalent to the plan's ordering. Marius Timmer, Lukas Kreft, and Arne Scheffer; reviewed by Mike Blackwell. Some additional hacking by me. |
