WL#10726: Ellipsoidal ST_Area

Affects: Server-8.0   —   Status: Complete

ST_Area currently only supports computations in Cartesian spatial reference systems (SRSs). This WL extends ST_Area to detect that its parameter is in a geographic (ellipsoidal) SRS and to compute the area on the ellipsoid.

Projected SRSs and SRID 0 will still return the same result as before. If the SRID refers to a geographic SRS, the result will be different.
