Postgres table "item" has int8 primary key "item_id".

Postgres table "image" has int8 foreign key "item" referencing
"item"->"item_id".

Table "item" is represented on  an Access form "item".

The form has a subform for the records in "image."

If form is opened with an empty "item" table, or if table is populated and
"New Record" button is pressed, error dialog "Error: ODBC call failed"
appears.

PsqlODBC log is attached. Here are the pertinent lines:

conn=47268416, query='SELECT "Item"."image_id" FROM "image" "Item" WHERE (
'' = "item" ) '
ERROR from backend during send_query: 'ERROR:  Bad int8 external
