Description
I would like to request a version of copy_records_to_table that will produce a PGCOPY format file.
Parameters:
- output – A path-like object, or a file-like object, or a coroutine function that takes a bytes instance as a sole argument.
- records – An iterable returning row tuples to copy into the file.
- columns (list) – An optional list of column names to copy.
- schema_name (str) – An optional schema name to qualify the table.
- timeout (float) – Optional timeout value in seconds.
Thanks!

Research direction
Start by reading the existing copy_records_to_table implementation and the PostgreSQL COPY/PGCOPY format requirements. Define how the requested output, records, columns, schema_name, and timeout parameters should work, then verify that the resulting file is valid PGCOPY data and supports the listed output forms.
