Yes you can, you have to define a service with a IP address, so when
the service postgres is relocated in the passive node also the IP
And you have also to develop a scripts that linux-ha cluster will use
in order to know if the service is working.
We adopted this solution with the help of a SAN attached with fiber
channell (this assure us that only one node can be attached to
the common storage) and all is working fine.
