> I'm working on implementing native MVT output support in PostGIS in the
> form of an aggregate function called ST_AsMVT.

> My motivation, besides itch scratching, is that existing toolchains:
>
> 1. assumes mercator. I'm finding use for vector tiles in other projections.
> 2. could be more efficient by doing work closer to the data source which
> is important if doing large amounts of precaching.
>
> I still have ways to go but I've got experimental Geobuf output working
> which has some shared properties. My continuing effort lives at
> https://git.osgeo.org/gogs/postgis/postgis/pulls/5 and constructive
> discussions are ongoing on the PostGIS list.
