 Keep in mind that ``bpython`` requires more system dependencies installed than
 plain ``odoo``.
 
+Note that Odoo forbids using the ``postgres`` user to connect to the database.
+But in some containerized environments (Docker), using ``postgres`` can be
+both safe and handy. In such case you would need to patch the Odoo server as
