How many PostgreSQL services? (swg-empire.de)

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.

Have you tried limiting the RAM usage of those containers? They tend to use as much as you give them, which is all of it by default.

That was more or less the default of the PostgreSQL container and it ran like ass because I don't have a SSD.

Basically I had to give MySQL a ton of RAM for Nextcloud and PostgreSQL for Lemmy. For now I've put both on the same PostgreSQL instance and let them battle out who gets the assigned RAM by themselves.
