> It's worth noting postgis has exported to mapbox vector tiles for some time (ST_AsMVT).
It's pretty conceivable to use ST_AsMVT now in QGIS to power a layer or two. We use QGIS pretty extensively to work with PostGIS tables already, so the ability to see the data in prerender stage (raw geometries) and all the middle and end stages (processed geometries and MVTs) we want is super powerful for anyone wanting to work with vector tiles and PostGIS.
qGIS has to be one of the standout open source projects these days up there with firefox. Its great to see.
