@ -201,14 +201,20 @@ a && b Overlaps
The cubements a and b overlap.
a @ b Contains
a @> b Contains
The cubement a contains the cubement b.
a ~ b Contained in
a <@ b Contained in
The cubement a is contained in b.
(Before PostgreSQL 8.2, the containment operators @> and <@ were
respectively called @ and ~. These names are still available, but are
deprecated and will eventually be retired. Notice that the old names
are reversed from the convention formerly followed by the core geometric
datatypes!)
Although the mnemonics of the following operators is questionable, I
preserved them to maintain visual consistency with other geometric
data types defined in Postgres.
