box2d — The type representing a 2-dimensional bounding box.
box2d is a spatial data type used to represent
the two-dimensional bounding box enclosing a geometry or collection of geometries.
For example, the ST_Extent aggregate function returns a box2d object.
The representation contains the values xmin, ymin, xmax, ymax.
These are the minimum and maximum values of the X and Y extents.
box2d objects have a text representation which looks like BOX(1 2,5 6).
This table lists the automatic and explicit casts allowed for this data type:
