PostgreSQL 14+ Pipelining Support

PostgreSQL 14 introduced the ability to Pipeline queries.

Are there any plans to support this with asyncpg in any capacity? At the time of writing, I’m looking to optimize large numbers of inserts and updates, and pipelining seems like it could be an interesting solution. I checked the existing issues and didn’t seem to find anything related to this so I thought I’d open a fresh issue/feature request.

Pipelining is already supported via executemany.

Pipelining only makes sense if you are sending lots and lots of queries as is the case with bulk insert. For regular queries it makes very little sense in the face of substantial implementation complexity, cancellation issues etc. In your case you can trivially emulate pipelining by querying both tables at the same time like so:

    comments, edits = await conn.fetchrow('''
        select
           (select array_agg(comments.*) from comments where user_id = 5),
           (select array_agg(edits.*) from edits where user_id = 5)
    ''')
