PostgreSQL ODBC driver v09.06.0100 and newer does not work with Teiid Server 9.1.1

This is an OBIEE 12c/unixODBC error:

Looking at the source code for the ODBC drivers, it seems that switching from CC_send_settings to CC_send_query for setting various settings does not work with Teiid.

# grep -r -i --include *.c DateStyle psqlodbc-09*
psqlodbc-09.05.0400/connection.c:       CC_send_settings(self, "SET DateStyle = 'ISO';SET extra_float_digits = 2");
psqlodbc-09.06.0100/connection.c:       res = CC_send_query(self, "SET DateStyle = 'ISO';SET extra_float_digits = 2;" ISOLATION_SHOW_QUERY, NULL, 0, NULL);
psqlodbc-09.06.0200/connection.c:       res = CC_send_query(self, "SET DateStyle = 'ISO';SET extra_float_digits = 2;" ISOLATION_SHOW_QUERY, NULL, 0, NULL);
psqlodbc-09.06.0300/connection.c:       res = CC_send_query(self, "SET DateStyle = 'ISO';SET extra_float_digits = 2;" ISOLATION_SHOW_QUERY, NULL, 0, NULL);
psqlodbc-09.06.0310/connection.c:       res = CC_send_query(self, "SET DateStyle = 'ISO';SET extra_float_digits = 2;" ISOLATION_SHOW_QUERY, NULL, 0, NULL);

I'm not sure if the bug is with the ODBC driver or this was an intentional change that Postgres Server can deal with and therefore Teiid server should be able to deal with.
