MS Access will not take any ODBC SQL data type and translate it into a check box.
Other tool may do this but not MS Access. Access only supports check boxes on
Access databases.
As for what Access it will do - The psqlodbc driver as options to treat postgresql
bools as SQL_CHAR (t/f) or or SQL_BIT. MS Access displays SQL_BIT as -1/0.
If you are not using the psqlodbc driver, you are on your own.
