I think we should be careful to think about upgrade considerations when adding this functionality. Bumping the module version number to add new functions is less likely to break things for users than changing the return value of an existing SRF. Maybe that's too far down in the weeds to worry about, but it's a thought - especially for pg_freespace, where there's no real efficiency benefit to have the same function look at the FSM and the VM anyway. -- 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
