[postgis-users] need a point in a polygon like centroid but in the polygon

[Larry Reeder]

I think what you're looking for is ST_PointOnSurface:
http://www.postgis.org/docs/ST_PointOnSurface.html

But be aware that this may generate a point on the edge of the
polygon, but not inside it, so that ST_Intersect is true, but
ST_Within fails.
