[postgis-users] Status and plans regarding circular arcs support?

[Paul Ramsey]

Hi Andrea,
In terms of "native" support for arcs, I believe the answer is "area,
length, distance, indexes and supportive output formats", full stop.
Everything else that accepts them does linearization.
In terms of future improvements, I know of no ongoing work,
particularly in the realm of things like constructive geometry or full
predicate support. Unfortunately it's always been a somewhat narrow
niche.
ATB,
P
