I am undertaking a project to upgrade our Postgresql production database from 9.1 to 9.3 using Londiste.
The reason I choose Londiste is to avoid substantial downtime from restoring the dump file or using pg_upgrade.
I have to upgrade 5 interconnected instances on separate servers at the same time. And, I am testing it on our test db servers.
From this website, I know that someone has used Londiste to upgrade to Postgres higher version before.
So, I would appreciate if anyone can share his/her experience here.
Thanks
