My lemmy instance seems to be using a lot of storage, I am the only one using it and for like 10 minutes a day. it's currently using about 122 gb, after about 3 months of usage

 ~/l/volumes> sudo du -d 1 -h  .
47G	./pictrs
75G	./postgres
0	./lemmy-ui
122G	.

seeing the usage of other ppl this seems really big? Am i doing someting wrong? edit: it is also using a lot of memory, i dont know exactly how much but it seems to be most of my system's available ram (16 gb)
