## Browse and manipulate the database
When the [matrix admin API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api) and the other tools do not provide a more convenient way, having a look at synapse's postgresql database can satisfy a lot of admins' needs.
First, set up an SSH tunnel to your matrix server (skip if it is your local machine):
```
# you may replace 1799 with an arbitrary port unbound on both machines
ssh -L 1799:localhost:1799 matrix.DOMAIN
```
Then start up an ephemeral [adminer](https://www.adminer.org/) container on the Matrix server, connecting it to the `matrix` network and linking the postgresql container:
```
docker run --rm --publish 1799:8080 --link matrix-postgres --net matrix adminer
```
You should then be able to browse the adminer database administration GUI at http://localhost:1799/ after entering your DB credentials (found in the `host_vars` or on the server in `{{matrix_synapse_config_dir_path}}/homeserver.yaml` under `database.args`)
⚠️ Be **very careful** with this, there is **no undo** for impromptu DB operations.
