The following documentation comment has been logged on the website:

Description:
The **uniq** function in the **intarray** extension removes **adjacent**
duplicates from an integer array. The documentation[0] about this behavior
is correct, but the example is a bit misleading, because it sorts the array
before applying uniq. The sort can be overlooked **easily** and leads to the
impression that **uniq** removes all duplicates from the array.
I propse to change the example to somthing like that:
uniq('{1,2,2,3,1,1}'::integer[]) → {1,2,3,1}
It might be a good idea to refer to the **sort** function in case one wants
to remove all duplicates.
Cheers, Martin Kalcher
