I was aware of that, but I wasn't aware of how many places that bleeds into until I checked just now. It would be nice if we could figure out how to make it obvious that the idioms around the use of long for work_mem stuff are idioms that have a specific rationale. It's pretty confusing as things stand. -- Peter Geoghegan
