I'm curious, what would be the recovery strategy for PITR master-slave
replication should the master fail (assuming hot fail over/backup)? A
simple dump/restore? Are there/is there any facilities in PorstgreSQL
for PITR archival which prevents PITR logs from be recycled (or perhaps,
simply archived off)? What about PITR streaming to networked and/or
removable media?
