      Change processing of extended-Query mode so that an unnamed statement · 5983a1aa
      Tom Lane authored
      that has parameters is always planned afresh for each Bind command,
      treating the parameter values as constants in the planner.  This removes
      the performance penalty formerly often paid for using out-of-line
      parameters --- with this definition, the planner can do constant folding,
      LIKE optimization, etc.  After a suggestion by Andrew@supernews.
