Symfony version(s) affected

6.4

Description

• Ubuntu 25.04
• PHP 8.4
• Symfony 6.4
• Docker Desktop

Newly installed Guestbook application (from Symfony Book). Here web and docker support added.
Cannot work with docker container as it is written in Book (see steps to reproduce).
It is not a problem of PostgreSQL, because I can enter into psql both from outside (host=localhost) and from inside docker container (host=app).

How to reproduce

1. Install Guestbook as symfony new guestbook --version=6.4 --php=8.4 --webapp --docker
2. Start docker as docker compose up -d.
3. Inspect Guestbook running containers by docker ps | grep guest:

4. Try to work with containerized database by symfony run psql:

psql: error: connection to server on socket "/var/run/postgresql/.s.PGSQL.5432" failed: No such file or directory
	Is the server running locally and accepting connections on that socket?
