That is not among the choices offered by ODBCConfig; I can take 6.4,
6.3 or 6.2.

Editing the ~/.odbc.ini file by hand, indeed it "solves" the issue. As
does completely removing the "Protocol = ..." line.

That is also not among the choices offered by ODBCConfig; I have the
following boolean choices:

ReadOnly
RowVersioning
ShowSystemTables
ShowOidColumn
FakeOidIndex

I'm fairly sure ODBCConfig does not have these options (and possible
values) hardcoded, but gets them by interrogating the driver (or
rather its companion libodbcpsqlS.so?); 't would be a good idea to
keep that in sync with what the actual driver supports.
