read-only queries on PITRslaves, any progress?

Hello,

this might not be the best place to ask, but has there been any further
progress or an alternative project to Florian Pflug's SoC 2007 proposal
about enabling PITR slaves to serve read-only queries? It seems like an
elegant way to load-balance a PostgreSQL database with very little overhead.

This was the original thread:

Thanks,
