Hi there,
I have polygons with 5 points (left, center, right, top, bottom)
Now I would like to select an individual point out of the polygon. Are there
any functions to provide this in an readable manner other than:
e.g. SELECT replace(split_part(p::text,',(',1),'((','(')::point as point FROM (
SELECT
'((0.001329116037,0.007391900417),(0.001371765621,0.1608393682),(0.1502391498,0.00733744679),(0.001500387404,-0.1468751078),(-0.1472653422,0.007425591447))'::polygon
as p) as poly
è (0.001329116037,0.007391900417)
Thanks
Andreas
