One thing I am concerned is, PostgreSQL's comment represents that
particular parameter's default value, not that the parameter is not
necessary. But unlike Pgpool-II, PostgreSQL does not provide
purpose-specific configuration files. Thus commenting out parameters
could be a good idea for Pgpool-II.
