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?
