Okay.  I failed to note the first time through that while the patch uses the
same option names for RAISE and GET STACKED DIAGNOSTICS, the existing option
lists for those commands differ:

--RAISE option--    --GET STACKED DIAGNOSTICS option--
ERRCODE             RETURNED_SQLSTATE
MESSAGE             MESSAGE_TEXT
DETAIL              PG_EXCEPTION_DETAIL
HINT                PG_EXCEPTION_HINT
CONTEXT             PG_EXCEPTION_CONTEXT

To be consistent with that pattern, I think we would use COLUMN, CONSTRAINT,
TABLE, TYPE and SCHEMA as the new RAISE options.
