There is no such error message within Postgres itself, so I suppose
Access is generating it --- or possibly the Postgres ODBC driver.
You might try asking on pgsql-odbc.

I'm guessing Access (or perhaps the ODBC driver itself) is issuing a SET
command or similar that isn't valid in that context.

Make sure error logging is on in your postgresql.conf and see what the
server-logs show is causing it.

Oddly, in the source I have to hand (8.0), I don't see the "operation is
not supported within transactions" error message in the source. This
means it could be the ODBC driver or Access itself giving the error.
