 Postgres is a heavier database format, which is useful for larger instances where you need to scale performance, or where you need to run your database on a dedicated machine separate from your GoToSocial instance (or do funky stuff like run a database cluster).
 
-GoToSocial supports connecting to Postgres using SSL/TLS. If you're running Postgres on a different machine from GoToSocial, and connecting to it via an IP address or hostname (as opposed to just running on localhost), then SSL/TLS is **CRUCIAL** to avoid leaking data all over the place!
+You can connect to Postgres using either a Unix socket connection, or via TCP, depending on what you've set as your `db-address` value.

 When you're using Postgres, GoToSocial expects whatever you've set for `db-user` to already be created in the database, and to have ownership of whatever you've set for `db-database`.
