By changing proxy_worker_stat * to a void * and arranging the

scoreboard.
This sounds reasonable to me as the stats should be available across process
boundaries and relying on the scoreboard is simple but puts on a few constraints
(especially when things should be extended). Furthermore I think that the
scoreboard
is sometimes in the danger of being used as the dumping ground for shared memory
requirements of all kind. But I do not think that is had been designed for that
task.
OTH not using the scoreboard does not free us from the need of managing the

of arbitrary balancer private data in the shared memory, because hardcoding
does not
seem to be an option for me.
Once the shared data is accessed via a small API nothing prevent us
going on using the scoreboard but will allow to use any other shared
storage.

the
error log?
Easy. See enclosed patch.
Thanks for the patch, but I don't think that we actually should change the
behaviour
as your patch does. This could break existing configs (how stupid they are).
So I would prefer only logging a warning that this is a bad configuration.
Agreed I will fix that and commit it.
