Default PostgreSQL 9.1 with synchronous replication

From http://h-online.com/-1341228

Quote:
The main innovation in version 9.1 of the free database server PostgreSQL, is synchronous replication. Synchronous replication ensures that, for each write transaction, the master waits until at least one slave node has written the data to its transaction log. This increase in reliability comes at the cost of longer response times, but can now be limited to individual transactions. While the superuser used to be the only one who could launch replication, the new privilege replication can be assigned to any user or role.
