There are many environment variables which libpq automatically uses.
Which variables should not be used for SR connection? All?

If both primary_conninfo and environment variables are not given,
the default value (e.g., port = 5432) is automatically used for SR
connection. Is this OK? or NG as well as the environment variables?
