If certain constraint characteristic clauses (NO INHERIT, NOT VALID, NOT ENFORCED) are given to CREATE CONSTRAINT TRIGGER, the resulting error message is ERROR: TRIGGER constraints cannot be marked NO INHERIT which is a bit silly, because these aren't "constraints of type TRIGGER". Hardcode a better error message to prevent it. This is a cosmetic fix for quite a fringe problem with no known complaints from users, so no backpatch. While at it, silently accept ENFORCED if given.
