I wasn't aware of this issue, and it certainly makes the whole latency
side of pgbench pretty useless on Win32. There is code in
src/include/executor/instrument.h that uses a higher resolution Windows
timer API than gettimeofday() does (as you point out, that one is only
resolves to one Windows tick, about 15ms). If I can get a Windows build
environment setup, I'll see if I can borrow that solution for pgbench.
