I vote against (c). I'm not sure which of (a) or (b) is better. We've talked about allowing foreign tables to inherit from regular tables and visca versa, and certainly, in that situation, tableoid would be useful. But I don't think we've made a definitive decision about that. I stripped that functionality out of the original patch because it introduced a bunch of warts that we didn't have time to figure out how to fix, and it's not clear to me that anyone's spent any time thinking about that since then. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
