Hi! The release notes indicate what, if any, steps are required to upgrade: http://www.postgresql.org/docs/current/static/release-9-1-9.html The "Upgrading a PostgreSQL Cluster" page in the docs http://www.postgresql.org/docs/current/static/upgrading.html has indications on when data upgrades are required.
