* contrib/hbpgsql/postgres.c
    ! guard PQEXECPARAMS() wrapper from generating unrecoverable error
      on empty parameter array "hb_xgrab requested to allocate zero bytes"

  * contrib/hbpgsql/tpostgre.prg
    ! corrected buggy parameter order in TPQserver():Query()

    * make TPQQuery, TPQRow classes more aware of NIL to NULL conversions,
      added support for inserting and updating empty xBase date value
      should fix issue #234, oRow:FieldPut( <n>, NIL ) also looks good
