Uses the same hexagon tiling concept as ST_HexagonGrid , but generates just one hexagon at the desired cell coordinate. Optionally, can adjust origin coordinate of the tiling, the default origin is at 0,0.
Hexagons are generated with no SRID set, so use ST_SetSRID to set the SRID to the one you expect.
