Обсуждение: Upgrade from 8.4
I am planning to upgrade my Postgres DB server from v8.4 to a newer version. Should 9.2 be a good choice for upgrading, it has the best features around replication. Also can someone help me with a guide for the upgrade process and rollback process in case anything fails.
Thanks,
Rajiv

Yes, PostgreSQL 9.2 would be an excellent choice; There are various upgrade options available like dump/restore, slony and pg_upgrade where each have their pros and cons. The selection of upgrade method solely depend upon the data size and available downtime. It's strongly recommended to test upgrade method before live implementation.Thanks & Regards,Prashanth RanjalkarDatabase Consultant & ArchitectOn Thu, Apr 18, 2013 at 4:40 PM, Rajiv Kasera <rajiv.kasera@pinelabs.com> wrote:I am planning to upgrade my Postgres DB server from v8.4 to a newer version.

The DB size is around 11-12 GB. Yes I am planning to take a downtime for upto 1 hour if required. I would like to understand the rollback steps if things go murky.
Thanks,

Hey,
you haven't told us anything about your database size or if any downtime is acceptable, generally a pg_dump and reload should work without any problem but it requires downtime,if you need more specifics you should give us more details.
