Remarks
The ST_Envelope function returns a geometry representing the minimum bounding rectangle (MBR) of the input spatial object. The envelope is always axis-aligned (parallel to coordinate system axes) and is returned as a polygon (or point/line for degenerate cases). This is the same as the bounding box. Useful for quick spatial indexing, extent calculations, or initial filtering in spatial queries. OGC-compliant.
