Redis extension doesn’t save to different buckets

So far, I’m very happy with the upgrade including Redis as mechanism to cache pages, objects and database queries. However, I have configured several databases to store every kind of cached object in its own redis database, i.e.: page cache in DB 1, database queries in DB 2, object cache in DB 3. But no matter if I enable persistent connections or not, it puts everything into DB 1, always.

I hope a crash is a hard thing to happend since all the keys are prefixed with the hostname and the number of the supposed DB, but anyway it is not expected, since I’d like to being able to fix a caching issue, for example, just emptying the page cache with FLUSHDB on one redis bucket, but I can’t actually do this because the plugin its putting all in the same database.

I’m storing the PHP sessions in different redis buckets, 17 and 18, so I’m pretty sure it is not the extension.

Any help would be very appreciated.
