I want to migrate my Nextcloud instance from MariaDB over to PostgreSQL. I already have a PostgreSQL service running for Lemmy. And I’m pretty starved for RAM.

Would it be better to just have one PostgreSQL service running that serves both Nextcloud and Lemmy? Or should every service have its own PostgreSQL instance?

I’m pretty new to PostgreSQL. But in my mind I would tend towards one service to serve them all and let it figure out by itself how to split resources between everything. Especially when I think that in the long run I will probably migrate more services over to PostgreSQL (and upgrade the RAM).

But maybe I am overlooking something.

Edit: Thanks guys, I’ve settled for a single instance for now. And after a little tuning everything seems to be running better than ever, with room to spare.

    In a hobby it’s easy to get carried away into doing things according to “best practices” when it’s not really the point.

    I’ve done a lot of redundant boilerplate stuff in my homelab, and I justify it by “learnding”. It’s mostly perfectionism I don’t have time and energy for anymore.
