[Tile-serving] [osm2pgsql-dev/osm2pgsql] Ideas for improved geometry processing (Issue #1663)

[Jochen Topf]

Here is another use case worth mentioning: Large oddly-shaped geometries can make indexes really inefficient. Think of an L-shaped linestring covering a large part of the map or a C-shaped polygon. Their bounding boxes can be much larger than the actual geometry, so any index lookup in that bounding box will hit that shape only to be later filtered out.
