when i am trying to insert the data using copy_records_to_table
i have encountered an error PostgresSyntaxErrror, and the error is ** syntax error at or near "STDIN"*
i dont know what to do, i have tried all of the me

Start at the copy_records_to_table entry point and try to reproduce the reported syntax error near "STDIN" with asyncpg 0.25.0, Python 3.9, and the stated Redshift environment. The report needs a complete reproducible case and a maintainer-confirmed outcome before a newcomer can know whether the result should be a fix or compatibility documentation.
