I can test pg_dump... for you, easy to do. I do about 5-10 pg_dumps a day
on windows while developing.

Also, I have an AWS instance I created to build PG/Win with readline back
in November.
I could give you access to that... (you are not the only person who has
made this statement here).
I've made such instances available for other Open Source developers, to
support them.

Obvi I would share connection credentials privately.
