Hi
You can use st_closestpoint(geom, st_centroid(geom)) to make sure that the
returned point is in most circumstances at or near the centroid, and always
at least on the boundary of the polygon. While st_pointonsurface certainly
will be faster, it will often choose a more random point on the surface.

Hi,
Use st_pointOnSurface (

Hi people, i need your help, i was using st_centroid to get a point that
be inside a polygon butr st_centroid got a property that is a problem to
me, it returns a point that not always is inside the polygon, cause when
the polygon has an irregular form, the point that st_centroid is outside
the polygon, and i need a function that do a similar thing that st_centroid
but i need that the point it returns always be inside the polygon, is there
a function that do that?
cheers.
