Hi there,

I was wondering how can we perform an extent over the international date

ST_Shift_Longitude seems perfect to compare 2 polygons over the IDL but
what if I have 3 points (let say 2 in Alaska and 1 in Russia) and I want
the get the extent?

e.g. SELECT st_extent(
ST_GeomFromText('MULTIPOINT(162.06 56.144, -140.808 66.07, -153.301

Returns: BOX(-153.301 56.144,162.06 66.07), the longitude -140 was no
included due to IDL.
