CAVEAT EMPTOR: It is always advisable to have a valid pg_dump/backup before
proceeding with pg_upgrade.
pg_upgrade is faster than a reload, but in the event of unexplained
problems, a backup is always good to have as a last resort.
Also, practice upgrading in a development environment before attempting to
do so in production.

Hi Subhan Alimy,

I would recommend that, in an environment apart from production (maybe your
DEV env), you should:

1. install PG 9.4 in a different dir than PG 9.1
2. create a new cluster, apart from dev/test/qa/etc in a new data dir
3. do a dump from the PG 9.1 cluster
4. restore the dump to the PG 9.4 cluster
5. test your application on the new cluster

Given that you have enough storage space on the production environment, you
could use the same approach to upgrade your prod database.

Regards,

Felipe
