I kind of wonder if it wouldn't be even better to just *delete* that from the thing altogether and write: function 1 (oidvector[], oidvector[]) of operator family array_ops for access method gin We're trying to represent the pg_amproc entry here, and including a bunch of details of the pg_proc entry to which it happens to point seems almost better to be confusing the issue. The key for pg_amproc is the operator family, the left and right argument types, and the proc number, so it seems like those are the things we ought to be printing. But if you want to keep it, by all means let's put it at the end. -- 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
