Hello Robert,
And this one generates a core dump:
\set cid debug(-9223372036854775808 / -1)
Floating point exception: 8 (core dumped)
That does not seem acceptable to me. I don't want pgbench to die a
horrible death if a floating point exception occurs any more than I want
the server to do the same. I want the error to be properly caught and
reported.
Please note that this issue/bug/feature/whatever already exists just for
these two values (1/2**128 probability), it is not related to this patch
about functions.
sh> pgbench --version
pgbench (PostgreSQL) 9.5.0
sh> cat div.sql
\set i -9223372036854775807
\set i :i - 1
\set i :i / -1
sh> pgbench -f div.sql
starting vacuum...end.
Floating point exception (core dumped)
I do not think that it is really worth fixing, but I will not prevent
anyone to fix it.
