Has this dataset been dumped and restored in the past? This looks like
the symptom from having had an older pg_dump drop a piece of the foreign
key information. Current sources should actually work for this case,
but if you want you can set tgconstrrelid manually for the affected
pg_trigger rows or drop the triggers and re-add the foreign key
constraints. The information was somewhat optional in the past but
became used in 7.3
