MS Access 2000 w/ PGSQL 8.0.x

I am having some issues when trying to query for booleans from Access
to Postgres 8.0.x. If I change to use Bools as Chars then I am
unable to delete from a table with a boolean in it, as postgres cannot
convert from boolean to char. If I do not use bools as chars then I
get "cache lookup failed for function 0"

I have followed what the tech docs have recommended to do with adding
the new msaccessbool function and = operator
(http://techdocs.postgresql.org/v2/Guides/Using%20Microsoft%20Access%20with%20PostgreSQL/view#55)

But to no avail!

Any help would be greatly appreciated.
