Comment:

 ST_Buffer in geography is not a native function.  It piggy backs on
 geometry ST_Buffer and in doing so chooses a best guess spatial reference
 system for the point before applying the buffer.  That said for large
 buffers, its going to have more and more errors as your buffer size grows.

 This is not a bug just an implementation limitation. As noted in the docs
 - http://postgis.net/docs/manual-3.0/ST_Buffer.html all assumptions full
 apart with large buffers.
