Commit77c168a

Remove grammar productions for prefix and postfix % and ^ operators,
as well as the existing pg_catalog entries for prefix and postfix %.These have never been documented, though they did appear in one oldregression test. This avoids surprising behavior in cases like"SELECT -25 % -10". Per recent discussion.Note: although there is a catalog change here, I did not force initdbsince there's no harm in leaving the inaccessible entries in one'scopy of pg_operator.
