To the best of my knowledge, there isn't one really. The buildfarm 
script has for a long time copied the *pq.dll to the install bin 
directory, and added the latter to the PATH. This might be a belt and 
braces (that's "suspenders" for Americans) approach, but it's worked for 
a long time ;-) There is probably a good case for "make install" to do 
this copy on Windows.

I have not seen this. When I get a chance I will try to reproduce it.

You built this natively, not with a cross-compiler, right?

No, it *uses* psql. If "make check" is working then so is psql. There is 
zero chance of it working with a broken psql.
