Documentation of return values of range functions lower and upper

The following documentation comment has been logged on the website:

Page: https://www.postgresql.org/docs/13/functions-range.html
Description:

Table 9.54 in page
https://www.postgresql.org/docs/current/functions-range.html states that the
functions lower and upper return NULL if the requested bound is infinite. If
the element type of the range contains the special values infinity and
-infinity, this is not correct, as those values are returned if explicitly
used as either bound.
