In my previous business, we used to do the same thing (buy state data, make it relational and sell it) with Postgres 6.5. It kept on crashing and losing data, so I moved it to MySQL. That worked ok... until I bought their isampack utility to compress the data tables (making them read-only) at which point it worked extremely well, and took up very little disk space. If I were to do it today, I'd definitely be using PG 7.1.3, regardless of disk space usage. I think if you analyze your field types you might find some wasted space there. MySQL tends to convert all CHAR fields to VARCHAR whenever there is any dynamic sized field in the table. Perhaps doing that for PG will help reduce your size. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Vivek Khera, Ph.D. Khera Communications, Inc.
