psqlODBC 'ERROR: invalid input syntax for integer: "A"'

Hello PostgreSQL gurus!

Can someone please help me solve this problem please?

I'm using Microsoft Access 2000 (9.0.6926 SP-3) to access (PostgreSQL) 7.4.6
via the psqlODBC drivers (both versions 7.3.02 and 8.0.0101).  The table I'm
accessing, "trx", has a primary key "id" column defined as a custom domain,
"id_dom".  The relevant DDL code is below.  When I attempt to link MSAccess
to the postgres table, I receive an error in the connection log: 'ERROR:
invalid input syntax for integer: "A"'.  I've pasted more of the error log
below.  I have several other tables with this same "id" column definition
and the ODBC driver is choking on those tables, yet it is connecting
properly to other tables (ones which don't have the "id" column).

I've searched http://search.postgresql.org/ and Google on this error to no
avail.  I suspect this problem relates to the integer / single quote issue
referenced in previous posts.  It may also relate to the domain I created,
but I'm not sure how to proceed.

I would like to get this ODBC driver connecting properly.  Can anyone please
help?

Thanks in advance!
