I think you probably need to provide a lot more detail about what you
are doing for anyone to have a chance of helping you with it.

Have you tried turning on row versioning in the data source?

I think the msysconf error is not related to your issue:

http://archives.postgresql.org/pgadmin-support/2002-01/msg00035.php

Can you query data from the data source using MS Excel?

No.  You probably need someone more knowledgeable than myself!  Now that
you have narrowed down the problem, someone should be able to help.

You will need to provide more details about your system.  i.e. operating
system, PostgreSQL server version, driver version (I assume ODBC), and
MS Access version...

What version of the PostgreSQL client libraries are you running.  There
is a bug in anything before 8.4 that would unlink libpq from memory and
not remove the SSL callback functions in that code.  When other
libraries attempt to shutdown their SSL, it crashes as those functions
point to invalid memory.  I've not seen this on the Windows platform
personally yet.  But I have seen it running php on linux.  Have a look
at " libpq does not manage SSL callbacks properly when other libraries
are involved." reported by me on 25/6/08.

Russell
