Hmmm. I see it at

  http://www.postgresql.org/users-lounge/index.html

Perhaps you looked elsewhere, or you saw an old mirror? (In any event, you
can get to the pgsql-interfaces archive at 

  http://www.postgresql.org/mhonarc/pgsql-interfaces/

which is great place to catch up on all the ODBC/Access questions of the
past.)

Haven't seen this exact error before.

Are you sure that you found and turned off BOTH read-only options in the
ODBC driver configuration? (I'm just wondering if this "can't
create" error is a strange read-only twist.)

Also, you might try to take the error at face value: try to create an
index on the Org field using psql, and see if you run across any errors.

The nicest Windows tool is pgAdmin, a fantastic tool to administer almost
every aspect of your PG database under Windows. You can find it at
www.greatbridge.org. It can be a *bit* tricky to install, as it has a few
prerequisites, but I think you'd find it worth your time.

Slimmer but less featureful is Zeos Database Explorer, available at

  http://www.zeos.dn.ua/eng/index.html

This is basically a GUI version of psql.

Either of these tools will let you try your query out from the Windows
box, and will help us figure out whether this is a PG problem, an
ODBC problem, an Access problem, etc.

My advice?

Get a Windows querying tool *other* than Access to just test the basics of
the ODBC connection, and post your results from that.

Also, you should compare your ODBC setup to the basic setup described in
the Pg+Access FAQ at www.scw.org/pgaccess, and write to the interfaces-
list with your settings, as well as a small pg_dump of your database so
that people can try to recreate your problem.

Good luck!
