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.
