Is it possible to remove a referential integrity trigger without dropping
tables? I tried to DROP TRIGGER using the name of the trigger created from
the foreign key clause when the table was created, without success (no such
trigger name).

Unfortunately dropping and recreating tables is not an option as it is a
production system. Therefore I don't want to get too reckless destroying
things in case I trash the entire database.
