Circle created using ST_Buffer displays elongated on map

[المشرف العام]

I am buffering a point to create a circle in PostGIS like:

ST_Buffer(geo::geometry, .0002, 8)

However, when displaying the polygon in Bing maps it ends up a vertically oriented ellipse or elongated circle.

Since both the Geography datatype and Bing both use the WGS84 datum, this is unexpected.
