Default Username and port should be correctly set

creating a new session and switching network type should correctly change the username and the port.

when switching between mysql and mssql, the port is correctly set (3306 and 1433 (where i assume that 1433 is the default port for mssql, i don't know it))

switching to postgresql keeps the user as root and the port on 3306 or 1433 but it should be "postges" and "5432"
