That you can't do. The usual recipe for this is something like
optimistic locking -- for instance, set an int8 column to
nextval() of some sequence, and then later, when you're ready to
commit, check to make sure the value hasn't changed and do all your
work in an SQL transaction. If the value has changed anywhere, you
know you have to throw away the work you did (or present the
intermediate changes to the user, or whatever).
