Similar to issue #94

I am trying to set up a query using ($1) and passing an argument. I am running into an issue when trying to pass a list of sets. Is there a way to format this query like the last example?

query = [(0,0), (1,1), (2,2)]

works:    await conn.fetch('SELECT * FROM table WHERE (a, b) IN ((0,0), (1,1), (2,2))')

works:    await conn.fetch('SELECT * FROM table WHERE (a, b) IN ' + str(tuple(query)))

fails:    await conn.fetch('SELECT * FROM table WHERE (a, b) IN ($1)', '((0,0), (1,1), (2,2))')

fails:    await conn.fetch('SELECT * FROM table WHERE (a, b) IN ($1)', str(tuple(query)))

works:    await conn.fetch('INSERT INTO table (a, b, c, d) VALUES ($1, $2, $3, $4)', a, b, c, d)

Thank you

この issue の再現例から始め、issue #94 と比較し、PostgreSQL の行値 IN 式で使用されるパラメーターを asyncpg がどのように扱うかに焦点を当てます。記載されている Python、PostgreSQL、Windows の環境で、成功するクエリと失敗するクエリを再現します。サポートされる動作と必要な引数形式が確立または文書化されれば完了です。
