@(box2df,box2df) — Returns
TRUE if a 2D float precision bounding box (BOX2DF) is contained into another 2D float precision bounding box.
@ operator returns
TRUE if the 2D bounding box A is contained into the 2D bounding box B, using float precision. This means that if A (or 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.
