I think this is a bug in 6.4:
bray=> select rcname, rcsrc from pg_relcheck where rcrelid = '115404'::oid and
rcrelid in (select min(rcrelid) from pg_relcheck group by rcname);
ERROR: parser: Subselect has too many or too few fields.
The subselect only produces one column; so I think that the error message
is wrong.
