Thread: Example for intersection operator is wrong

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/9.2/static/functions-range.html
Description:

On the page https://www.postgresql.org/docs/9.2/static/functions-range.html
it gives an example for the intersection of range (5,15) and range (10,20)
as [10,15). But 10 isn't included in the second range; the actual output of
this operator is [11,15).

Uh, no, it isn't:

regression=# select int8range(5,15) * int8range(10,20);
 ?column?
----------
 [10,15)
(1 row)

You'd be correct if int8range(10,20) produced '(10,20)', but it produces
'[10,20)'.
