      Fix handling of NULL constraint conditions: per SQL92 spec, a NULL result · 6d1efd76
      Tom Lane authored
      from a constraint condition does not violate the constraint (cf. discussion
      on pghackers 12/9/99).  Implemented by adding a parameter to ExecQual,
      specifying whether to return TRUE or FALSE when the qual result is
      really NULL in three-valued boolean logic.  Currently, ExecRelCheck is
      the only caller that asks for TRUE, but if we find any other places that
      have the wrong response to NULL, it'll be easy to fix them.
