## Development Tasks
### Connecting to the database
Assuming you're running the the default configuration with `foreman start`,
open an interactive session with Postgres via:
```console
$ psql --host localhost --port 64444 hydra
```
### Runinng the builder locally
For `hydra-queue-runner` to successfully build locally, your
development user will need to be "trusted" by your Nix store.
Add yourself to the `trusted_users` option of `/etc/nix/nix.conf`.
On NixOS:
```nix
{
nix.trustedUsers = [ "YOURUSER" ];
}
```
Off NixOS, change `/etc/nix/nix.conf`:
```conf
trusted-users = root YOURUSERNAME
```
