Re: How do I drop a Complicated Constraint Trigger After Delete Execute Procedure?

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"
Attribute | Type | Modifier

----------------------+-----------------------+-----------------------------------
-------------
user_id | integer | not null default nextval('users_pk
_seq'::text)
user_name | text | not null default ''

Indices: idx_users_username,
user_user,
users_user_pw

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.

> Here is the bug table. Please NOTE there is no constraint listed in the bug table.

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.
