Formatting rows for copy_to_table?

[robhaswell]

• asyncpg version: 0.22.0

Does asyncpg contain any code that would format tuples suitable for consumption in copy_to_table? I can see that copy_records_to_table should somehow format the tuples into the COPY FROM format but I can't see where this happens.

My use-case is that I am trying to use COPY FROM with an async iterator.

Thanks.

Yes. The magic happens in copy_in in protocol.pyx, and copy_records_to_table exists exactly for this purpose. Adding support for async iterables there shouldn't be hard.
