Closed richtia closed 11 months ago

PR to add new geometric data types and functions.

Thanks for the feedback @paleolimbot! For now i'll stick with just adding a new geometry extension type you suggested. That also makes the new function specs easier.

@EpsilonPrime i'll update the description for st_makeline, the geometries shouldn't be entirely arbitrary, they should both either be a point, a multipoint (collection of points), or a linestring (points that are already connected to each other)
