Changing the INT8 AS option has no effect on version 07.03.0100.

BUT, I could confirm that using the snapshot version 07.03.0107 with:

1) "INT8 AS default" the field is mapped in Access 2002 as "Numeric" of
type "Decimal" Size 19 Scale 0.

2) "INT8 AS varchar" the field is mapped in Access 2002 as "Text" Size 19,
that was the behaviour of the legacy driver.

In both cases no errors are returned.

Excellent

Please try the snapshot dll at
http://www.geocities.jp/inocchichichi/psqlodbc/
or change the *INT8 AS" DSN option.
