Plain vacuum should suffice, provided the FSM settings are enough for your database: > maxfsmpages 480001 (6 bytes each) > maxfsmrelations 30000 (70 bytes each) max_fsm_pages at 480000 are enough to cover 3 GB, if my math is correct. It may be enough or it may not, depending on the dynamics of your data. Also with non-full vacuum you may be able to get away with vacuuming some tables more often. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc.
