And \d will show the real names of the triggers, so it's not really
that hard to drop them:

u=# \d t1
      Table "public.t1"
 Column |  Type   | Modifiers 
--------+---------+-----------
 f1     | integer | not null
Indexes:
    "t1_pkey" PRIMARY KEY, btree (f1)
Triggers:
    "RI_ConstraintTrigger_229629" AFTER DELETE ON t1 FROM t2 NOT DEFERRABLE INITIALLY IMMEDIATE FOR EACH ROW EXECUTE PROCEDURE "RI_FKey_noaction_del"('<unnamed>', 't2', 't1', 'UNSPECIFIED', 'f2', 'f1')
    "RI_ConstraintTrigger_229630" AFTER UPDATE ON t1 FROM t2 NOT DEFERRABLE INITIALLY IMMEDIATE FOR EACH ROW EXECUTE PROCEDURE "RI_FKey_noaction_upd"('<unnamed>', 't2', 't1', 'UNSPECIFIED', 'f2', 'f1')

u=# drop trigger "RI_ConstraintTrigger_229629" on t1;
DROP TRIGGER

I do recall newbies forgetting to double-quote the mixed-case trigger
names when this came up in times past, though.
