As I understood the report, it was not "things completely fall over",
it was "performance gets bad". But let's get real. Unless the OP
has a machine with thousands of CPUs, trying to run this way is
counterproductive.
Perhaps in a decade or two such machines will be common enough that
it'll make sense to try to tune Postgres to run well on them. Right
now I feel no hesitation about saying "if it hurts, don't do that".
