Remarks
The ST_Centroid function returns a point representing the mathematical centroid (center of mass) of the input geometry. For polygons, this is the center of gravity assuming uniform density. For lines, it's the center of the line's extent. For multi-part geometries, it's the weighted center of all parts. Note that the centroid may not lie within the geometry itself (e.g., for C-shaped polygons). Useful for labeling, finding centers, or proximity analysis. OGC-compliant.
