It depends on how this feature is supposed to be used exactly. A replication plugin might very well be loaded via session_preload_libraries and not appear in SQL at all. In that case you need some C-level hook. In another case, an extension might want to inspect relation options from user-space triggers. So you'd need to register some SQL-level function for option validation. This could end up being two separate but overlapping features. -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
