 Demo usage:
- - the CDC'ed database must pre-exist, it should first be created as follows
- - run `cd cdc`
- - run `docker run -p 5432:5432 -v ./postgres-data:/var/lib/postgresql/data -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=postgres postgres:12.16`
- - using a postgresql client, create the 'test_db' database and a table
- - Ctrl-C the docker container started above
- - now run `docker compose up -d`
- - checking configuration:
 
-   - from docker desktop, open a terminal to redis container
-   - from that terminal, run `redis-cli SUBSCRIBE test_db_changes`
-   - using a postgresql client, perform some inserts, updates or deletes in the 'test_db' database
