✏️ Last week we noted that Postgres 15 was likely to drop on October 13 and that this issue might be delayed. However, there's speculation it might be delayed to October 20. Given this, we're sending this issue today and if Postgres 15 does get released tomorrow, we'll send a quick, extra 'newsflash' email to let you know.
