Yeah, in my case I had to write ugly IFs using unlang to detect
whether an sql node is down so that FR would go to the next sql node.

If this is a dedicated FR-only mysql cluster, a poor-man's workaround
would be to have several SQL nodes, with FR running on each node, and
have each FR only access its own sql node.
