I am using Databricks Mosaic, where I am parsing an OSM PBF file and trying to convert it into spatial geom types [line, point, polygon, etc.].
I am able to process the relation having one outer polygon with st_makepolygon(outer,inner[]) function. However, I am unable to create a spatial geom with multiple outer polygons.
Tried using st_union on the geom array, but that doesn't work!
