Another idea:
Has anyone tried to put the WAL segment directory on a cluster
filesystem and use that for cold (perhaps even hot) failover?
The archive script could apply completed wal segments to the backup
node. If the primary node fails, the last (partial) segment is applied
as well and the backup node is activated.
