Unreliable results returned with PostgreSQL Spatial query?

Does the ST_Intersects function have problems returning the correct
results with non-box type geometries, like a circle polygon or other style
polygons.

i.e.

select count(*) from doti_sensors_report where
ST_INTERSECTS(sensor_location, ST_Buffer(ST_MakePoint(21.304116745663165,
38.68607570952619)::geography, 4000));

st_intersects is distributed with postgis and not directly with Postgres,
hence this issue would be better discussed from here:
