Reorganize Postgres access (breaking change)

Browse Source 
In short, this makes Synapse a 2nd class citizen,
preparing for a future where it's just one-of-many homeserver software

If you are using an [external Postgres server](configuring-playbook-external-postgres.md), the above tool will not be available.
By default, this tool puts you in the `matrix` database, which contains nothing.
To see the available databases, run `\list` (or just `\l`).
To change to another database (for example `synapse`), run `\connect synapse` (or just `\c synapse`).
You can then proceed to write queries. Example: `SELECT COUNT(*) FROM users;`
**Be careful**. Modifying the database directly (especially as services are running) is dangerous and may lead to irreversible database corruption.
When in doubt, consider [making a backup](#backing-up-postgresql).
