Hisham, I just saw the merge has been accepted. I'm glad it helped.
I'd like just to remember there's another issue regarding the library
naming difference between unix and windows ('pq' shall be specified on unix
while 'libpq' must be used on windows).
I couldn't examine this issue but I'd like to remember that it still
occurs. Today, I need to edit the rockspec by hand in order to install the
lib.
Thank you
Regards.
