如何在 postgresql 中存储 Arraylist 数据

Question

I am trying to write Arraylist<String> to postgresql.我正在尝试将Arraylist<String>写入 postgresql。 but getting below error.但低于错误。

ERROR: column "data" is of type character varying[] but expression is of type bytea
  Hint: You will need to rewrite or cast the expression.

If someone knows which data type i should use for column to store arraylist content in postgresql?如果有人知道我应该使用哪种数据类型作为列在 postgresql 中存储数组列表内容？

Thanks谢谢
