I believe the "box" type description is slightly incorrect: # \dT box Liste der Datentypen Schema │ Name │ Beschreibung ────────────┼──────┼────────────────────────────────────────── pg_catalog │ box │ geometric box '(lower left,upper right)'
While the syntax '((3,4),(1,2))'::box works, the canonical spelling is '(3,4),(1,2)' and hence the description should be: geometric box '(lower left),(upper right)' Christoph
