Well, we replicate a 1 TB database between two locations.
It is a fairly active OLTP application, but certainly not
pushing the limits of what PostgreSQL can do in transactions
per second.
But I get the impression that replication is widely accepted
and used by now.

Don't use synchronous replication if you have a high transaction
rate and a noticable network latency between the sites.
Wait for the next bugfix release, since a nasty bug has just
been discovered.
