Feature request: copy_records_to_file

[austinnichols101]

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!
