Hi,

I have just tested PSQLODBC-libpq version 8.01.00.02 with MS Access, and
until now, I have not noticed anything special compared to the non-libpq
version. Thanks to all who support the driver.

A bug has appeared with version 209 of the driver, and has not been
corrected since then. It is apparently linked to foreign encodings.
Version 208 of the driver does not suffer from that at all. That's the
one I use for production at the moment.

The libpq version has the same problem. When opening certain records, MS
Access fails with error '2467': the expression references an object that
was closed or deleted. Or sometimes: "You tried to affect the NULL value
to a variable that is not of type Variant."

Here is some log output. Tell me if there is any specific test I can do
for you, in order to track down the bug.

Regards,

Philippe
