devenv up exit with a 0 status code even if postgresql fails to start with an error

[bbigras]

Describe the bug

If I run devenv up the command exits without any error message. It would be nice to have an error exit code and the ERR line from the log.

❯ cat /tmp/process-compose-bbigras.log
25-01-21 01:49:23.436 INF Process Compose v1.40.1
