With the following query ```sql INSERT INTO people (name) VALUES ($1) RETURNING id ``` and values to create `[('anne',), ('ben',), ('charlie',)]`. I believe there's currently no way with asyncpg to execute this single query and get all the ids returned. I've tried: * `executemany` but the result is discarded * `fetch` but that doesn't extend to executing many * `fetch` while casting the argument to an array `::TEXT[][]` but I either get a syntax error or a single value of the stringified list insert. In short: would it be possible for `executemany` to return the result?
