Setting connections with environment variables

[sel-carlitos]

I am trying to get this working:

    "sqltools.connections": [
        {
            "previewLimit": 1000,
            "server": "db",
            "port": 5432,
            "driver": "PostgreSQL",
            "name": "db_container",
            "database": "${env:POSTGRES_DATABASE}",
            "username": "${env:POSTGRES_USER}",
            "password": "${env:POSTGRES_PASSWORD}",
        },
    ],
    

But I can get it work. Is there a way I can achieve this?
