pg_trigger.tgtype question
I was wondering if there was a way, given the information in pg_trigger,
specifically pg_trigger.tgtype, to find out on what events a trigger is
fired, and whether it is fired before or after those events.
I've looked through the code a little in src/backend/commands/trigger.c
and think I'm on the right track, thanks to some help given to me on the
#postgresql irc channel, but I'm not much of a C programmer and I'm not
very familiar with postgresql internals.
Basically I'm looking for a way to connect to a postgres database and get
back all the stored procs (which I can do), triggers (which I can do), and
when those triggers fire (which I haven't figured out).
Thanks.

Hi Brian,
Just look at the pg_dump source code.
In 7.4, there will be a pg_get_triggerdef function that will return the entire CREATE TRIGGER statement for a trigger, but that's a ways off yet.
