<grin> As you probably guessed, the purpose of these procedures is to
take a large amount (about 60mb) of not-normalized data from ELBS and
normalize it for our web-based case management system.

What's really frustrating about it is that we're only going to be doing
this for 2-3 months before we jettison ELBS for reasons that should be
obvious to you. But for those 2-3 months, the data transfer needs to
work well, and right now it doesn't even finish.

Well, I'll try 128 and see if that helps any.

Yeah. I was planning on that -- as well as the postgresql.conf tuner
-- as soon as I can get through one data transfer so that I have a
little working time.
