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.
