I did finally get most of the data dropped into the Postgres database. It's
now sitting at 55,000 email messages (100MB).
Even with a huge mix of records, search time is not impacted as far as I can
tell. Queries come back just as quickly as they did before.
I did discover that indexes on the text fields are not being used when I use
a Regex operator. So I dropped the index with no performance hit.
Thanks to everyone for their input,
