This problem can appear when querying information schema views like
<literal>referential_constraints</>, <literal>check_constraints</>,
<literal>domain_constraints</>, and
<literal>check_constraint_routine_usage</>. Some other views have

<literal>constraint_table_usage</>, <literal>constraint_column_usage</>.
