True, but if we are out of space we are going to crash anyway because
we can't allocate new heap pages, write regular (text) logfiles,
update CLOG and other SLRU-based structures, etc. So if it is "less
bad" the difference seems to be negligible - either way you crash.
Unless I'm missing something of course.
