Because most of the processing in set_config_option is independent of
the type of the GUC variable. Maybe it could be refactored, but I don't
think it would come out prettier, nor faster. Again, the important code
paths are starting from string values anyway --- I don't think we should
contort the design of guc.c to serve a small minority of callers at the
expense of complicating the normal cases.
