What constitutes "failed" as far as this is concerned?

Like the PgJDBC approach I wonder how much this'll handle in practice
and how it'll go with less clear-cut failures like disk-full on a
replica that's a member of the failover pool, long delays before
no-route-to-host errors, dns problems, etc.

Had any chance to simulate network failures?
