Postgres already has a asynchronous log shipping replication system similar to MySQL's, but the rub is that you can't read from the slave, so it's only good as a "warm standby" solution.
Work was happening to make it possible to read from the slave, and this was meant to go into 8.4. However, there were some issues and it got pulled from the release.
Hopefully we'll see it in 8.5. This is the only real way MySQL is beating Postgres at the moment.
