One way (the only one I could think of) is to dump the schema using the
custom format and then use the pg_restore to list the contents of the
dump file:


pg_dump --format=c --schema=a_schema --schema-only --file=x.dump a_database

and then:

pg_restore --list x.dump


Probably someone would suggest a more direct way.

I've always thought this syntax a little strange but:

\dt my_schema.  (tables)
\df my_schema.  (functions)

The period at the end is required.

For triggers there is no \ command (at least in 8.1) that I know of
so you can use a view I found somewhere - wish I could give proper
credit but can't remember where I found this.

I modified the original one to join in pg_namespace which allows you
to limit the view to show only triggers for a particular schema:

      create view my_schema.showtriggers as
    select trg.tgname as trigger_name, tbl.relname as table_name,
          p.proname as function_name,
           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, pg_proc p, pg_namespace nsp
    where trg.tgrelid = tbl.oid
          and trg.tgfoid = p.oid
          and nsp.oid = tbl.relnamespace
          and nsp.nspname = 'my_schema'
        order by relname, trg.tgname;

Replace that line above "and nsp.nspname = 'my_schema'" to use your
schema name.
