Problems with Access XP and text primary keys - Mailing list pgsql-odbc

I've been using Postgres 8.0rc5 with the pgsqlODBC 8.00.00.03 driver and am
having some problems.

The database works correctly for some time but suddenly and for no reason I
can find I get #Deleted in some of the fields. These tables seem to be those
which have text primary keys. I've looked at the psqlodbcXXXX.log and it
seems that I get:

conn=162845400, query='SELECT "mw"."users"."user_name" FROM "mw"."users" '
[ fetched 13 rows ]

conn=162845400, query='SELECT
"user_name","entered_ts","entered_user","last_changed","last_user","full_name","area_id","xmin"
FROM "mw"."users" WHERE "user_name" = 'b' OR "user_name" = 'c' OR
"user_name" = 'm' OR "user_name" = 'b' OR "user_name" = 'p' OR "user_name" =
't' OR "user_name" = 'j' OR "user_name" = 'r' OR "user_name" = 'f' OR
"user_name" = 'j''
[ fetched 0 rows ]

conn=162845400, query='SELECT
"user_name","entered_ts","entered_user","last_changed","last_user","full_name","area_id","xmin"
FROM "mw"."users" WHERE "user_name" = 'p' OR "user_name" = 'p' OR
"user_name" = 'j' OR "user_name" = 'j' OR "user_name" = 'j' OR "user_name" =
'j' OR "user_name" = 'j' OR "user_name" = 'j' OR "user_name" = 'j' OR
"user_name" = 'j''
[ fetched 0 rows ]

instead of when working correctly:

conn=170998744, query='SELECT "mw"."users"."user_name" FROM "mw"."users" '
[ fetched 13 rows ]

conn=170998744, query='SELECT
"user_name","entered_ts","entered_user","last_changed","last_user","full_name","area_id","xmin"
FROM "mw"."users" WHERE "user_name" = 'btrewern' OR "user_name" =
'chappellj' OR "user_name" = 'mcwilliamsf' OR "user_name" = 'ben' OR
"user_name" = 'postgres' OR "user_name" = 'timc' OR "user_name" = 'jasonc'
OR "user_name" = 'robh' OR "user_name" = 'francism' OR "user_name" =
'janeh''
[ fetched 10 rows ]

conn=170998744, query='SELECT
"user_name","entered_ts","entered_user","last_changed","last_user","full_name","area_id","xmin"
FROM "mw"."users" WHERE "user_name" = 'pons_temp' OR "user_name" = 'pauls'
OR "user_name" = 'jeremyw' OR "user_name" = 'jeremyw' OR "user_name" =
'jeremyw' OR "user_name" = 'jeremyw' OR "user_name" = 'jeremyw' OR
"user_name" = 'jeremyw' OR "user_name" = 'jeremyw' OR "user_name" =
'jeremyw''
[ fetched 3 rows ]

The table "mw"."users" is created as:

CREATE TABLE users
(
  user_name short_text_dom PRIMARY KEY,
  entered_ts timestamp DEFAULT ('now'::text)::timestamp(6) with time zone,
  entered_user short_text_dom DEFAULT "current_user"(),
  last_changed timestamp,
  last_user short_text_dom,
  full_name text,
  area_id int4 NOT NULL
);

and

"mw"."short_text_dom" is:

CREATE DOMAIN short_text_dom
  AS varchar(250);

Does anyone have any ideas?
