Thanks for replying. I've got a message into to my team asking if I need
to de-identify some of the table names before I go submitting output to
a public mailing list.

In the meantime, again I'm new to this -- I got pg_stats; which rows are
  the relevent ones?

Also, I am running postgresql-server-7.4.9 from FreeBSD port (with
optimized CFLAGS turned on during compiling)

OS: FreeBSD 5.4 p8

Thanks,
