Hi,
PostgreSQL allows to use version-specific configuration files, which
allows to change some settings only for particular version of DB.
I think a similar enhancement would be nice and usable for
administrators of MySQL as well.
Please, consider the attached patch as a simple proposal. Any comments
are welcome.
Cheers,
Honza
