I don't think this is right.  If the original tuple was inserted by a
subtransaction of our transaction, it will have been checked at
subtransaction subcommit, no?  ISTM what we need is to schedule the
on-UPDATE trigger if the original tuple was inserted by either our
current (sub)transaction or one of its parents, and those are not the
semantics of TransactionIdIsCurrentTransactionId, unfortunately.

Stephan, have you looked at this bug report?  What do you think?
