If it's documented I think it's well hidden ;-) ISTM that the fact that
we implement FK constraints via triggers is really an implementation
detail, not something the user should be encouraged to mess with.

Probably not. ISTM that the scheme should turn tgisconstraint into a
multi-valued item (tgkind: 'u' = userland, 'c'= constraint, 'p' =
partition or some such).
