      The unnamed prepared statement is likewise planned during Parse processing
      if the Parse message defines no parameters.  But if there are parameters,
!     query planning occurs during Bind processing instead.  This allows the
!     planner to make use of the actual values of the parameters provided in
!     the Bind message when planning the query.
