Okay.  I will go off and do that, then come back to Dean's patch.
Proposed names:

        pg_trigger.tgconstrindid        analogous to tgconstrrelid
        pg_constraint.conuindid         analogous to confrelid

where the latter will be populated for any unique or pkey constraint.
The former will be always 0 for the moment, but we'll start filling
it in with Dean's patch.

(thinks...)  Actually, u for unique might be a poor choice if Jeff's
patch goes in and starts using it for things that aren't exactly
unique indexes.  Should it be just conindid?

                        regards, tom lane
