Lemmy instance using a lot of ram (reddthat.com)

I have my own Lemmy instance (Lemmy.emphisia.nl) but I had to take it offline, after running a while it was using more than half of the system memory (16gb in total). Causing the computer to crash as there are a lot of other services also running on it. The problem appears to come from postgress. In btop I can see it spawning a lot of processes all taking up about 80 MB in the beginning but rising as it runs, rising as high as 250 MB per process. I have already tried adjusting the postgress config to be optimized for less memory, but it seems to do nothing.

Is this normal, and if not, what is going wrong?

Yea, I had to make a crontab task that resets lemmy every day. Hope it gets fixed in the future but for now it sorta works.
