Yes, I have an ERROR message (either I didn't notice it before or it is
new):
NOTICE: Index pkex_ellipse_opto_proc: Pages 138; Tuples 30535. Elapsed 0/0

pqReadData() -- backend closed the channel unexpectedly. This probably means the backend terminated abnormally
before or while processing the request.
We have lost the connection to the backend, so further processing is
impossible. Terminating.
It looks like the error is either occuring on table ex_ellipse_opto_proc or
the next table in the list ex_ellipse_proc. However, I think the error is
more general than that. It appears to occur just before the last table in
the database gets vacuumed. Here's the list of my tables:

Yesterday, I was adding tables in one by one from a previous pg_dump. The
error didn't pop up until after I had about 9 or 10 tables restored. I
didn't think about it then, but it may have always occured after the second
to last table in the list. But don't hold me to that.
In any case, I'll try to re-build everything like you've asked to get a
better error message. Maybe if I go through step-by-step again. You'll be
able to help me find where the error is taking place.
Thanks Tom and Oliver. I'll get back to you when I finish the rebuild.
