Bezier curves (the regular kind) cannot represent circles and ellipses, this is true. However, rational Bezier curves can [1]. I don't know if PostScript has a rational Bezier primitive, but some drawing libraries do. A prominent example of a library that does is Skia, the rendering engine behind Chrome and Android.
