[feature request:] use postgis databases instead of raster images for maps

[conrad-heimbold]

"PostGIS is an open source software program that adds support for geographic objects to the PostgreSQL object-relational database. PostGIS follows the Simple Features for SQL specification from the Open Geospatial Consortium (OGC)."

Benefits:

• rendering seems to be faster than with raster images (only tested in Osmand and TilelessMap)
• you can easily select which layers to show and hide (less distraction)

"Proof-of-Concept" implementation:
TilelessMap ( https://github.com/TilelessMap/TilelessMap ) .

For start, this app is not using raster images.

And it is not a feature request - it is an unfinished proposal to completely rearrange internal implementation.

[matkoniecz]

Also, is it possible to painlessly integrate database based rendering with tangram-es? How updating map data would work?

Without answers to this questions this proposal is incomplete and of very limited usefulness.

@conrad-heimbold Good you opened a new issue for that (from the side effect that this library also allows offline maps, see #122 (comment)).

So my comment from there:

Okay, but this would mean switching to a completely different rendering library, as far as I see. So this is not really realistic.
Also vectors can sometimes be bad for performance reasons (OsmAnd uses vectors AFAIK), but for the simple mapstyle of SC, it would likely not be so bad.
