Thanks for the test and precise analysis!

Sigh.

I do not think that putting such version requirements are worth it just
for the sake of pgbench.

In the attached version, I just comment out the call and add an
explanation about why it is commented out. If pg overall version
requirements are changed on windows, then it could be reinstated.
