Tt-rss and postgresql 13

I am running tt-rss with postgresql 9 as the backend but would like to upgrade postgresql to version 13 since it is used for other databases as well.

Is anyone using a postgresql 13 backend for tt-rss?

Ever since a few days after it was released.
haven’t seen any issues.

Same here. Note however that I’m not sure of migration fro 9 to 13. You probably should upgrade 9 -> 10 -> 11 -> 12 -> 13.

But using pg_upgrade is really simple.

can anyone layout steps to upgrade postgres 12 to 13 on centos 8
thank you.

This is not a postgresql forum. However, upgrading is entirely dependent on the way it is installed on your system. So there might not be one simple way to upgrade.
