I would also prefer the second approach, as i prefer to not change the
db_url syntax that much. There is already a small patch on the tracker
that implements this option . The author also mentioned the use case of
setting certain charsets.
Setting the group with a module parameter in the db_mysql module would
work. But as you said, this would not satisfy your requirements having
several unique groups in different modules. If the addition of the 'group'
db_url parameter could be done in a backward compatible way, then this
would be ok for me.
