This might help, got it from a project run by Great Bridge Software, now 
defunct, to create an Oracle like data dictionary for PostGreSql:

CREATE VIEW all_objects
AS
  SELECT  UPPER(pg_get_userbyid (cls.relowner)) AS owner
          ,UPPER(cls.relname) AS object_name
          ,CASE WHEN cls.relkind = 'r' THEN CAST('TABLE' AS VARCHAR(18))
                WHEN cls.relkind = 'i' THEN CAST('INDEX' AS VARCHAR(18))
                WHEN cls.relkind = 'S' THEN CAST('SEQUENCE' AS VARCHAR(18))
                WHEN cls.relkind = 's' THEN CAST('SPECIAL' AS VARCHAR(18))
                WHEN cls.relkind = 't' THEN CAST('TOAST TABLE' AS VARCHAR(18))
          END AS object_type
          ,CAST(NULL AS DATE) AS created
          ,CAST('VALID' AS VARCHAR(7)) AS status
  FROM pg_class cls
  WHERE (NOT cls.relhasrules
         AND NOT EXISTS (SELECT rul.rulename
                         FROM pg_rewrite rul
                         WHERE ((rul.ev_class = cls.oid) AND (rul.ev_type = 
'1'::"char"))
                         )
         )
  UNION ALL
  SELECT UPPER(pg_get_userbyid(cls.relowner)) AS owner
       , UPPER(cls.relname) AS OBJECT_NAME
       , CAST('VIEW' AS VARCHAR(18)) as object_type
       , CAST(NULL AS DATE) AS created
       , CAST('VALID' AS VARCHAR(7)) AS status
  FROM pg_class cls
  WHERE (cls.relhasrules
  AND (EXISTS (SELECT rul.rulename
               FROM pg_rewrite rul
               WHERE ((rul.ev_class = cls.oid)
               AND (rul.ev_type = '1'::"char")))))
  UNION ALL
  SELECT UPPER(pg_get_userbyid(p.proowner)) AS OWNER
       , UPPER(p.proname) AS OBJECT_NAME
       , CAST('FUNCTION' AS VARCHAR(18)) as object_type
       , CAST(NULL AS DATE) AS created
       , CAST('VALID' AS VARCHAR(7)) AS status
  FROM pg_proc p
  WHERE p.oid > 18655;

Yeah, same here...  Here is a test case where tables and views show up 
with the same relkind... :)


$ psql test -c "create table table1(id int); create view view1 as select 
* from table1;"
CREATE VIEW
$ psql test -c "select relname, relkind from pg_class where relname in 
('table1', 'view1');" | sed -e 's/r$/v/'
 relname | relkind
---------+---------
 table1  | r
 view1   | r
(2 rows)


But I believe this is a feature, not a bug. Look at this, it is 
explained here 
http://www.postgresql.org/docs/8.0/static/catalog-pg-class.html.
