Обсуждение: GROUP BY array

Hello All!

I am using arrays in my database widely.
When it will be possible to do: GROUP BY some_array?

As I read in 7.3 ORDER BY some_array will appear. Am I right?

GROUP BY (also ORDER BY) will work on any datatype that has '<'
and '=' operators.

Dunno where you read that.  AFAIK there is nothing in 7.3 for array '<'.
But you could write it yourself ...
