This "lab" image goes along with https://www.benburwell.com/posts/row-level-security-postgresql-views/.
To use it, simply start a container called
docker run --rm --detach --name rlslab benburwell/postgres-rls-lab
Then, you can connect to the database in the container using
docker exec -it rlslab psql -U postgres
Use Ctrl-D to exit
psql. When you're finished, don't forget to stop the
docker stop rlslab
