[postgis-users] Which operators/functions work with circular arcs?

[Paul Ramsey]

They aren't marked, perhaps Regina could garden test them to find them...
All the simple functions that take apart geometries, etc, work fine.
The simple measurements (length/perimeter) work fine
As of 2.2 all the GEOS-backed functions will "work" (by linearizing
the arcs before sending them in)
The simplification functions won't work, though as of 2.2 they too
will linearize first.
The area calculations don't work.

A comprehensive survey would be most appreciated.
