We have our production environment database server in Postgres 8.3 version. we have planned to upgrade to lastest version 9.1. Dump from 8.3 and restore in Postgres 9.1 takes more than 5 hours. Any other quick method to upgrade from 8.3 to 9.1. We need to reduce our downtime below 1 hour. Any Possibilities..?
Thanks in Advance.
