Is there actually a way to specify always compressing?

I do have a database that has both user-entered information as well as things like email addresses, so I could do some testing on that if people want. -- Decibel!, aka Jim Nasby [EMAIL PROTECTED] EnterpriseDB http://enterprisedb.com 512.569.9461 (cell)
