Hi there,
create table qq (b box);
CREATE TABLE
select count(*), b from qq group by b;
ERROR: could not identify an equality operator for type box
LINE 1: select count(*), b from qq group by b;
but following select works fine
select ' (43.6038,48.8664536),(1.3620777,1.44327)'::box = ' (43.6038,48.8664536),(1.3620777,1.44327)'::box; ?column?
---------- t
(1 row) ^
What does it means ?
Regards, Oleg
