Yep, that's all pieces of multi-year cross-project improvement. We spent some years on algorithms, then we lacked infrastructure, now postgres added infrastructure and after they push out we can start using it. You're welcome to join the ride and help testing. -- Darafei "Komяpa" Praliaskouski OSM BY Team - http://openstreetmap.by/
