[Feature Request] - PostgreSQL as remote storage (auth, data)

[devlikepro]

Right now we support MongoDB as a remote storage for auth and data about the session (messages, chats, etc) and sqlite as a local storage. Because of the nature of SQL (sqlite) and NoSQL (mongo) it's hard to implement new features, basicly we have to do the same thing in two words instead of one...

For that reason, we should add PostgreSQL as remote storage and start deprecating mongodb as remote storage. We won't do it fast, a year or so we definitely will support mongo Writing a tool to migrate MongoDB => PosgreSQL auth and data would also increase the process, but we'll see how it goes.
