Re: 7.5 beta version

Hi!

1) Is this depending on the server, or the fact that there is a
different libpq.dll in the path? Does a non-win32 client work against
the win32 server, and vice versa?

2) Are you using the import library from mingw, or the one from the old
visual C++ compile? If you are using the import library from the old
Visual compile, what happens if you change to the mingw one?
