Oh! I'd totally forgotten that thread, but given that discussion,
and particularly the counterexample at

https://www.postgresql.org/message-id/16807.1456091547%40sss.pgh.pa.us

it now feels to me like maybe this change was a mistake. Perhaps
instead of the committed change, we ought to go the other way and
rip out the infinity checks in numeric generate_series().

In view of tomorrow's minor-release wrap, there is not time for
the sort of more leisured discussion that I now think this topic
needs. I propose to revert eafdf9de0 et al before the wrap,
and think about this at more length before doing anything.
