Is there, or are we likely to see a way of calculating ST_Azimuth on the
spheroid?
Is an implementation, overloading ST_Azimuth to accept the GEOGRAPHY type to
be expected?
I suspect the code has already been written, given the existence of
ST_Distance_Spheroid which presumably uses Vincenty's
Indeed, the code is there, it just needs to be exposed to SQL. Do you
build your own PostGIS Francis? If so you can open a ticket for the
feature and I'll provide a patch there you can apply. If not, it could
be a long wait for PostGIS 2.0 and new features. (several months)
