How can I list defined triggers on PostgreSQL 7.1.3?

I'm using the following statement:

select trg.tgname, tbl.relname,
       case trg.tgtype & cast(2 as int2)
         when 0 then 'AFTER'
         else 'BEFORE'
       end as trigger_type,
       case trg.tgtype & cast(28 as int2)
         when 16 then 'UPDATE'
         when 8 then 'DELETE'
         when 4 then 'INSERT'
         when 20 then 'INSERT, UPDATE'
         when 28 then 'INSERT, UPDATE, DELETE'
         when 24 then 'UPDATE, DELETE'
         when 12 then 'INSERT, DELETE'
       end as trigger_event
from pg_trigger trg, pg_class tbl
where trg.tgrelid = tbl.oid
Have a look at: http://www.postgresql.org/docs/7.3/static/catalogs.html
