I think we can and must do better.
Yeah, that and the other reason I sort of gave up on this approach is that it is nearly impossible to find some good terminology that works for all callers of select_common_type() (VALUES, UNION, JOIN, IN, CASE, ARRAY, COALESCE, GREATEST, according to my notes). A pointer into the statement would certainly be much nicer. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
