to pg servers running on non-standard ports.
MDL-44862 postgres: tests to support socket & port

Both the database auth and enrol plugins use ADOdb
to perform connections. Socket and port are allowed
there if passed as "socket:port", so, when both are
configured in CFG, we pass them that way. Else
ADOdb defaults to standard port (5432).
