Add missing commutators for distance operators
Some of <-> operators between geometric types have their commutators missed. This commit adds them. The motivation is upcoming kNN support for some of those operators. Discussion: https://postgr.es/m/f71ba19d-d989-63b6-f04a-abf02ad9345d%40postgrespro.ru Author: Nikita Glukhov Reviewed-by: Tom Lane, Alexander Korotkov
