Ok. I typed the correct name this time, and got the same error.
"drop trigger bug_assigned_to_fk on users;
ERROR: DropTrigger: there is no trigger bug_assigned_to_fk on relation users "
"drop trigger bug_assigned_to_fk on bug;
ERROR: DropTrigger: there is no trigger bug_assigned_to_fk on relation bug"
Here is my user table:
\d users
Table "users"

user_id | integer | not null default
nextval('users_pk

Someone mentioned about using 'alter table'. Would like would work? But I'm
not sure how to do it because \d doesn't show the constraint.
Any ideas?

It looks to me like you misspelled the trigger name --- what you quote there is
bug_assigned_to_fk not bug_assign_to_fk. Also, the trigger is attached to
table users not table bug.

I think in 7.1 that trigger would be shown as a trigger if you did \d users,
but it's not going to be mentioned by \d bug.
