Hm, nothing very exciting in there.  But the known reasons for this
type of error involve something changing a table rowtype that the
function uses (that is, ALTER TABLE ADD COLUMN or the like).  Or
dropping/recreating such a table altogether.  Is there any part
of your workflow that redefines the type of
product_owner.external_sys_class_code_pres.audit_update_dt or
product_owner.external_sys_class_code_pres ?

Also, you still didn't tell us the server's version.
