In the review above Kyotaro-san suggested that message should contain
information on what it expects... So, maybe then
pg_log_error("\\watch interval must be non-negative number, but
argument is '%s'", opt); ?
Or perhaps with articles? pg_log_error("\\watch interval must be a
non-negative number, but the argument is '%s'", opt);
