Try limiting the database connection pool size too in lemmy.hjson. It helped a lot in my instance. I set mine to 30 in a small server with 8gb ram. You can set it to even lower value for lower postgres memory consumption.

database: {
        host: dbhost
        user: "lemmy"
        password: "secret"
        database: "lemmy"
        pool_size: 30
}
