I know *somewhere* I recently read something indicating a critical
configuration change for DSPAM + Postgres, but don't think I've seen it
mentioned on this list.  Possibly it is in the UPGRADING instructions
for 3.2.1, or in a README file there.  At any rate, it mentioned that
it was essential to make some change to the table layout used by previous
versions of DSPAM, and then Postgres would run many times faster.

Unfortunately I no longer have 3.2.1 installed on my system, so I can't
tell you if it was in there or somewhere else.
