Yeah, in any modern Postgres (9.6 or later) this calculation fails
with a numeric overflow in less than a millisecond for me. That's
consistent with the fact that numeric calculations were improved
somewhat in 9.6.
In older versions (9.0 - 9.5 inclusive), which includes 4 old
unsupported versions, it takes a little over a second to fail.
Certainly not an "infinity loop".
In really old versions (I tested 8.3 and 8.4) it does indeed appear to
go into an near-infinite loop, but frankly, anyone running 8.4 or
older has bigger problems.

Dean
