TIP 1: if posting
INTO test ( aname ) VALUES ( 'yourusername' );
CREATE RULE lock_test_user_update
AS ON UPDATE TO test
WHERE old.aname = CURRENT_USER
DO INSTEAD nothing;
CREATE RULE lock_test_user_delete
AS ON DELETE TO test
WHERE old.aname = CURRENT_USER
DO INSTEAD nothing;

the scope of currval() is.
The value of currval will be predictable within the current session.
I.E., if another session increments the sequence, the value returned by
currval in the current session won't change.
Best.

So that's the problem I'd like to prevent, for which I think this
function would be useful. So I'll hack at it and see what I come up
with. Might not happen immediately, though..

Can anyone suggest a more elegant way of finding foreign keys than
parsing the tgargs value returned by this query? I'd really rather do
pure SQL, sans string parsing, if possible.

The HTML programming documentation (e.g.
