How so? We shouldn't commonly acquire relevant locks while executing a query? With a few exceptions, they should instead be acquired t the start of query processing. We do acquire a lot of lwlocks, obviously, but we don't process interrupts during the acquisition / holding of lwlocks. And presumably the interrupt would just be processed the next time interrupt processing is happening? Greetings, Andres Freund
