There are also walmgr.py from Skytools and pitrtools from CMD, both of
them are simpler to install and get working. In my view the big ticket
with SR would be the synchronous part for full HA setup, without that I
guess walmgr+HS is plenty good enough. But as a project that still means
having to get an external piece of software to operate replication, so
that's still not "PostgreSQL 8.5 comes with replication support."
