Postgresql does support replication, in fact there are several different
varieties of it available, check out slony1 among others. What it
doesn't support is automatic failover.

What are you all using to cluster PostgreSQL? I looked at the master/slave
replication that comes with Postgres. It seems fine if you want to
replicate the data, but how do you get dbmail to switch databases when there
is a failure?
I'm currently using drbd to replicate the disk block device that my postgres
database is stored on, then only run postgres on the "primary" machine.
Linux heartbeat fails and starts the services on the "secondary" machine
shold the first one croak.
