1. Upgrade your storage. 160GB is nothing and 1TB SSDs are cheap
2. You could delete pictures, but then the posts are broken
3. You could archive old pictures. The pictures will have a longer load-time. Also I don’t think archiving pictures is a feature of lemmy, so you would have to implement it yourself

Edit: I think postgres is so big, because of backups. You could delete those, but that’s risky
