      Redesign DISTINCT ON as discussed in pgsql-sql 1/25/00: syntax is now · dd979f66
      Tom Lane authored
      SELECT DISTINCT ON (expr [, expr ...]) targetlist ...
      and there is a check to make sure that the user didn't specify an ORDER BY
      that's incompatible with the DISTINCT operation.
      Reimplement nodeUnique and nodeGroup to use the proper datatype-specific
      equality function for each column being compared --- they used to do
      bitwise comparisons or convert the data to text strings and strcmp().
      (To add insult to injury, they'd look up the conversion functions once
      for each tuple...)  Parse/plan representation of DISTINCT is now a list
      of SortClause nodes.
      initdb forced by querytree change...

      Replace typtoout() and gettypelem() with a single routine, · d03e9873

      so that fetching an attribute value needs only one SearchSysCacheTuple call
      instead of two redundant searches.  This speeds up a large SELECT by about
      ten percent, and probably will help GROUP BY and SELECT DISTINCT too.
