If you do it the other way around, a hot standby (see:  http://www.postgresql.org/docs/9.3/static/hot-standby.html) might work for you.

That is, your cron scripts would UPDATE the master server, and the Web site would do read-only queries against the slave server.

That’s for the built-in replication of PostgreSQL (sorry, I have no experience with the add-on replication solutions).
