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).
