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.

I recently upgraded from the 8.2 branch to 9.2. Since mine was so old the
only option I had was the dump/restore functionality, but that's really a
simple procedure, just potentially time consuming based on your data and
computers. It's also good to look over the release notes between the
versions so you can identify parts of your code (if you use things like
plpgsql). Doing a full dump and restore to a new version can point these
issues out, and you can properly test your applications and scheduled tasks
against your new server before taking the plunge.

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,
Rajiv

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.

Vasilis Ventirozos
