Can you try running against 8.4.1? I believe there are a number of
improvements that should help in your case. For one thing, the
max_fsm_pages and max_fsm_relation "knobs" are gone - it happens
automagically. I believe there are some substantial improvements in
space reuse along with numerous improvements not directly related to
your question.
