@(geometry,box2df) — Returns
TRUE if a geometry's 2D bounding box is contained into a 2D float precision bounding box (BOX2DF).
@ operator returns
TRUE if the A geometry's 2D bounding box is contained the 2D bounding box B, using float precision. This means that if B is a (double precision) box2d, it will be internally converted to a float precision 2D bounding box (BOX2DF)
This operand is intended to be used internally by BRIN indexes, more than by users.
Availability: 2.3.0 support for Block Range INdexes (BRIN) was introduced. Requires PostgreSQL 9.5+.
This method supports Circular Strings and Curves
This function supports Polyhedral surfaces.
