Listing Triggers

Greetings,

    I am sure I have seen this, but I have searched the docs, and
tried to search the archives, which was a definite exercise in futility.
How can I list the triggers on a specific table?  I tried the following:

=> select * from pg_trigger where tgargs like '%foo%' ;
ERROR:  Unable to identify an operator '~~' for types 'bytea' and 'unknown'
        You will have to retype this query using an explicit cast

The reason I ask is because I had a problem the other day.  I dropped a
table and the triggers didn't get deleted.  I couldn't do anything with
the other table the trigger was on because all of my constraints failed.
I had to go in and manually find and delete the triggers, which was not an
easy task.  Finding a couple needles out of 500+ triggers with no good
tools to help me was not fun.  HINT: I dumped pg_trigger with oid's to a
file, found the triggers using grep, and then deleted them by oid.
