catalog of postgres

Hi guys

i have a following query:

SELECT nspname as schema, relname as objeto
FROM
  pg_class bc,
  pg_attribute ta,
  pg_namespace ns,
  pg_type ty
WHERE
  ta.attrelid = bc.oid
  and ta.attnum > 0
  and not ta.attisdropped
  and nspname <> 'information_schema' and nspname not like 'pg_%'
  and relam = 0
  and bc.relnamespace = ns.oid
  and bc.relname not like 'pg_%'
  and ta.atttypid = ty.oid
  group by nspname, relname
  order by nspname, relname asc


with this query I obtain the schema name and the objects of this it , but
 like I can know that they are, that is to say if they are tables,
views, functions, sequences, etc ????????

thank  for all
