That's a good start, and I'm certainly going to hold on to this query. That gave me a good list of triggers and their functions. The info I'm still looking for is: on what events do the triggers get fired (insert, update, delete) and what do the functions do? in other words, the actual text of the create function statement that was used to create the function, or its equivalent. Sort of like a \d for functions. [ a short time passes ] Ok, I finally got pgAdmin installed and working, thanks to a couple of tips in the archives of this terrific group. It does show the definitions of functions, but has it stuck in a real tiny box. But at least it's there. And I also have the pg_dump -s option as well, which certainly ought to work. Looks like I have a couple of working solutions.

Wes, Is this the kind of "trigger text" data you were interested in? select relname as table_name, tgname as trigger_name, tgtype as trigger_type, proname as trigger_function from pg_class, pg_trigger, pg_proc where pg_class.oid = tgrelid and tgfoid = pg_proc.oid and tgisconstraint = 'f' order by table_name, trigger_name; Bernie wsheldah@lexmark.com wrote: > >Thanks for the reply.
