Comment(by pramsey):
Confirmed there is something fishy in st_intersects in 1.5/2.0. It's in
the point-in-polygon test, as seen here, the first point of the polygon
returns false
{{{
select st_intersects(
geog,
ST_GeographyFromText('SRID=4326;POINT(-95.9 42.9)')
)
from iowa
where name10 = 'Iowa';
}}}
