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.
