I'm trying to comb through my database and add ON DELETE CASCADE to a
number of tables where I already have fkeys in place, but I'm having a
hard time.
ALTER TABLE project_task DROP CONSTRAINT
"project_task_group_project_id_f" RESTRICT;
ERROR: ALTER TABLE / DROP CONSTRAINT: project_task_group_project_id_f
does not exist
ALTER TABLE project_taskADD CONSTRAINT projecttask_groupprojectid_fkFOREIGN KEY (group_project_id)REFERENCES
project_group_list(group_project_id)ON DELETE CASCADE;
NOTICE: ALTER TABLE will create implicit trigger(s) for FOREIGN KEY
check(s)
ALTER
That command works, but now I think I have 2x as many triggers as I
want. How do I get rid of the original triggers?

After adding the new foreign key:
Triggers: RI_ConstraintTrigger_51364957, ***new RI_ConstraintTrigger_51030049,
RI_ConstraintTrigger_51030047, RI_ConstraintTrigger_4305858, RI_ConstraintTrigger_4305852,
