  See doc/configurable_failover.    "redundant" means "go to next module
on fail"

  For SQL, this means no DB connectivity.

  It doesn't track that.  Each packet is independent of the other packets.

  In version 3, the new "connection pool" code should be able to handle
this.  It's not all there yet, but a loss of DB connectivity means that
the SQL module can quickly return "fail".
