Postgres Port already in use

[joao-parana]

When I tried to run the commands cd docker-compose/suite ; docker-compose up I got the error:

Error starting userland proxy: listen tcp4 0.0.0.0:5432: bind: address already in use

This is because I have a Postgres database running on the same host in bare-metal which I cannot disable.

How do I safely change the Postgres port in docker-compose YAML files? There must be other references that must be modified, but where ? Is there documentation for this?
