Don't recommend legacy geometry types

[Komzpa]

In the wild, there is no good reason to use postgres-bundled geometric types, they're misdesigned and create problems later.

@Komzpa so is the right thing to recommend PostGIS types instead? Or what's the best practice here?

[Komzpa]

@cevian pretty much, to use geometry/geography type instead. It's one of those things like json datatype that entered core before the right thing and now it's too late to drop it without breaking compatibility.
