Hi,
I'm looking for a software to migrate database between versions with minimum downtime.

which one can be used to do this job ?

Hi Isabelle,

There are multiple ways to do it.
The fastest way is probably pg_upgrade.

There are some difference ways to do it depending on what requirements you have on redundancy while upgrading.

I recently read an interesting real-life story from a very big company, Adyen, and how they upgraded their 50 terrabyte PostgreSQL database. The article is from 2018 but I still think it's relevant:

There might be other good tools I don't know of, I'm not an expert on upgrades.
Hopefully other pghackers can fill in.

Best regards,

Joel

This is not an appropriate topic for the hackers email list, which is
for internal server development discussion. The 'general' or 'admin'
lists would be better.
