I think that the C function could call get_call_result_type() and get the return type OID back via the second argument. > Also, are default arguments always applied in all the contexts where > this function might be called? Uh, I'm not sure. But I don't see why it would need different handling than any other function which takes default arguments. It shouldn't be needed during bootstrapping or anything funky like that. -- 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
