Running two RaceDB containers using the same Postgresql container

[stuartlynne]

For cyclocross events, we like to put out a self-service kiosk to let pre-registered people who already have their RFID tag and bib numbers to check-in.

Before containers, using SQLite we ran two copies of RaceDB. With the second copy having its own Impinj RFID reader and wands etc.

Is that supported with the current Postgresql / RaceDB style of containers? I.e. add a second RaceDB container which would use the same PostgreSQL database/container and be available at a separate port.

The alternative would be supporting two RFID readers in RaceDB.
