One store, two machines?

Greetings.

We would like to implement a PostgreSQL database in such a way that the data
are housed on disk volumes which are redundant across two Solaris (or maybe
Linux) hosts.  Both hosts must have write access to the store -- a master
system/backup system scheme is not acceptable for us; was also want this to
be a load balancing setup.

Does Postgres have a facility for keeping data stores on two hosts in sync?

TIA,
