Postgres' website mentions DRBD, but not on the data files.  They recommend
a setup with two servers sharing a common mount point (SAN or similar).
That common mount point has the data files.  The first server has postgres
running with DRBD pushing changes to everything other than the postgres data
files to the second server.  If the first server takes a dump, the second
server simply starts postgres and lets postgres do a recovery on the shared
mount and continue running.  (Also using Heartbeat to move the virtual IP.)

If you do get this working on the data files as well...I'd definitely like
to know what you did.  Having the common mount point with the data files is
the only thing that's kept me from trying this setup on my postgres
databases.
