i don't, i have the pleasure to work with a better (IMHO) environment ;)

postgresql does support sync replication, so you don't need a shared 
storage. just regular boxes with fast disks.
you failover the master role and the master role ip, lot easier than 
mount/umount filesystems and such.


there is a RA script for pacemaker which greatly simplifies the operation.
