That's something I'd very much like to avoid - being able to say
continue-until using the function would be very nice. Consider for
example doing this from pgadmin.
So I'm back to my original question which is, how much work would this
be? I don't know my way around that part so I can't estimate, and
what's there so far is certainly a lot better than nothing, but if
it's not a huge amount of work it would be a great improvement.
