我收到了另一个团队发来的列名列表。为了确保所有字段列名称在特定模式内有效，我将它们放入临时表中。我现在想看看它们是否存在。当我尝试加入 时information_schema.columns，我收到以下错误：
ERROR: 0A000: Specified types or functions (one per INFO message) not supported on Redshift tables.
Column "c.column_name" has unsupported type "information_schema.sql_identifier".
Column "a.*" has unsupported type "pg_attribute".
Column "t.*" has unsupported type "pg_type".
Function "format_type(oid,integer)" not supported.
Function "format_type(oid,integer)" not supported.

Function "has_table_privilege(oid,text)" not supported.
Function "has_table_privilege(oid,text)" not supported.
Function "has_table_privilege(oid,text)" not supported.
我尝试过塑造column_name不同的类型，但没有成功。有人可以告诉我出了什么问题以及我如何实现这个目标吗？
