Postgres replication solutions

Besides slony, is there any other postgres replication active project? I
I need a solution where I could mirror a database to a 'spare' server,
for statistical analysis (just SELECTs beeing done there), and 'lag'
between actuall data and the slave server synchronisation can be even
few hours.

It would be awesome if it's not trigger-based.

I looked on gborg.postgres.org, there are numerous replication projects,
but for most of them last activity was in 2002. On pgfoundry I found
nothing (I haven't spent much time there since the web-site is awfully
slow).

So, I'd like a recommendation.
