Hello Tom,
Nope, I'm 100% sure that the libpq.dll used is the one I just
compiled. And I never installed an older libpq.dll on this system.
My application loads specifically the libpq.dll I compiled (I use
the full library path on the call to LoadLibrary() call, so there is no way
it is an older library.
Eduardo Stern from dbExperts (http://www.dbexperts.com.br), a
PostgreSQL specialized consulting company, got the same results.
The ODBC driver, however, do not suffer from the same problem, once
it does not use libpq.
Maybe I should write a C sample that proves libpq under windows has
this bug ???
Best Regards,
Steve Howe
