出现EntityManager.createQuery不可理解错误的Postgres/PostGIS st_distance_sphere函数

import org.postgresql.util.PGobject;

// 获取数据库连接
Connection connection = entityManager.unwrap(Session.class).connection();

// 创建原生SQL查询
String sql = "SELECT st_distance_sphere(?, ?)";
PreparedStatement statement = connection.prepareStatement(sql);

// 设置参数
PGobject point1 = new PGobject();
point1.setType("geometry");
point1.setValue("POINT(1 2)");
statement.setObject(1, point1);

PGobject point2 = new PGobject();
point2.setType("geometry");
point2.setValue("POINT(3 4)");
statement.setObject(2, point2);

// 执行查询
ResultSet resultSet = statement.executeQuery();

// 处理结果
if (resultSet.next()) {
    double distance = resultSet.getDouble(1);
    System.out.println("Distance: " + distance);
}

// 关闭连接和结果集
resultSet.close();
statement.close();
connection.close();
