Right now, it might well be the case that ExecRelCheck is always called
in the per-query context. The point I was trying to make is that I'd
like to change the code so that we don't run so much code with current
context set to per-query context; at which point ExecRelCheck will fail
if it hasn't got that MemoryContextSwitchTo. So, yeah, it's work in
progress.
