...following on also from thoughts on [PERFORM] list...
Clearly running out of pre-allocated WAL space is likely to be the next
issue. Running out of space in the first place is likely to be because
of an intense workload, which is exactly the thing which also makes you
run out of pre-allocated WAL space. Does that make sense?
