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.dllI 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
sameproblem, 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
