Ah, true. But I figured that in the context of 2PC and replication that
most of the associated failures were likely to occur in an active
backend or something equivalent, where a stored procedure was likely to
be accessible.
But yes, you certainly want to account for failures where the database
itself is unavailable. So I guess my original comment isn't strictly
true. :-)
