Good idea.

Personally, I don't care about Windows enough. I want it to work, but
performance optimisation is beyond what I'm bothered with.

Another useful test would be to modify libpq as described above, so its
headers set __declspec(dllexport) on its exports during compilation and
its headers set __declspec(dllimport) when included while compiling
other binaries that will link to libpq. Then use *that* in pgbench too
and see if it makes any meaningful difference.
