END AS TABLE_TYPE, d.description AS REMARKS, ? as TYPE_CAT, ? as TYPE_SCHEM, ? as TYPE_NAME, ? AS SELF_REFERENCING_COL_NAME, ? AS REF_GENERATION FROM pg_catalog.pg_namespace n, pg_catalog.pg_class c LEFT JOIN pg_catalog.pg_description d ON ( c.oid = d.objoid AND d.objsubid = ? and d.classoid = ? :: regclass ) WHERE c.relnamespace = n.oid AND n.nspname LIKE ?
