Indeed, vacuum is going to be the biggest offender here, sadly. One could work around this of course (on top of my head, using notify to wake- up another client that would launch the required vacuums…) Being able to do transactions in DO blocks is a great new feature of v11 I was not aware of. But psql saw the addition of \if recently, so why not having loops in there too ? (Something better than this hack of course, it was just a 10 minutes hack-sprint for a demo) Regards Pierre
