But it's collection_type_identifier that you join against, say, columns, so you can resolve the element type of column types. So collection_type_identifier must match the dtd_identifier schema of columns etc., whereas element_types.dtd_identifier is not joinable against anything. -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
