And the other odd thing is that it fails to dump it as a trigger either.
The "invalid argument string" complaint indicates that pg_dump didn't
find the right number of "\000" sequences in the tgargs value; but
pg_get_triggerdef evidently is finding the right number of zero bytes.
It almost looks like the tgargs value got coerced from bytea to text
somewhere between the catalogs and pg_dump, but how'd that happen?

It'd be good to look at the trigger row directly:
select * from pg_trigger where tgname = 'RI_ConstraintTrigger_39053';
