As part of the upgrade, the database is dumped to `/tmp`, an upgraded and empty Postgres server is started, and then the dump is restored into the new server.
To use a different directory for the dump, pass some extra flags to the command above, like this: `--extra-vars="postgres_dump_dir=/directory/to/dump/here"`
To save disk space in `/tmp`, the dump file is gzipped on the fly at the expense of CPU usage.
If you have plenty of space in `/tmp` and would rather avoid gzipping, you can explicitly pass a dump filename which doesn't end in `.gz`.
Example: `--extra-vars="postgres_dump_name=matrix-postgres-dump.sql"`
**All databases, roles, etc. on the Postgres server are migrated**.
