Hmm, I can see having DROP DATABASE just stopping the autovacuum (since the work will be thrown away), but is a good idea to stop it on CREATE DATABASE? I think it may be better to have CREATE DATABASE wait until the vacuum is finished. -- Alvaro Herrera http://www.CommandPrompt.com/ The PostgreSQL Company - Command Prompt, Inc. ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
