Just checked if the problem still exists. It turned out that the base problem has been created by a odbcinst.ini entry which has referenced the wrong path. (This system here has undergone some debian releases).
The current psql-odbc does suggest the right path. Testing the configuration was sucessfull. Please close the bug. Regards -- Juergen Lueters -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
