Postgres: [pg on conflict method] does not support 'where' condition.

#[test]
fn test_pg_on_conflict() {
     let pg_dialect = PostgreSqlDialect {};
     let sql = r#" INSERT INTO distributors (did, dname, dsize)  VALUES (5, 'Gizmo Transglobal', 1000), (6, 'Associated Computing, Inc', 1010)  ON CONFLICT(did)  DO UPDATE SET dname = $1 WHERE dsize > $2"#;
     let mut ast = Parser::parse_sql(&pg_dialect, sql).unwrap();
}

The result after the test case is executed：

thread 'test_pg_on_conflicts' panicked at 'called `Result::unwrap()` on an `Err` value: ParserError("Expected end of statement, found: WHERE")',
