DROP_TRIGGER - remove a trigger

       The DROPTRIGGER statement in PostgreSQL is incompatible with the SQL standard. In the SQL standard,
       trigger names are not local to tables, so the command is simply DROP TRIGGER name.

DROPTRIGGER removes an existing trigger definition. To execute this command, the current user must be
       the owner of the table for which the trigger is defined.

       Destroy the trigger if_dist_exists on the table films:

           DROP TRIGGER if_dist_exists ON films;

       IF EXISTS
           Do not throw an error if the trigger does not exist. A notice is issued in this case.

       name
           The name of the trigger to remove.

       table_name
           The name (optionally schema-qualified) of the table for which the trigger is defined.

       CASCADE
           Automatically drop objects that depend on the trigger, and in turn all objects that depend on those
           objects (see Section 5.15).

       RESTRICT
           Refuse to drop the trigger if any objects depend on it. This is the default.
