It would be good to fix it I suppose, but what with VACUUM FULL being on
the edge of deprecation anyway, it's hard to muster enthusiasm for doing
a (probably) large additional amount of work on it, I think most
hackers would prefer to spend time on making it unnecessary than making
it more bulletproof.

Note that there is (AFAIK) no risk of loss of committed data from this
bug. The fact that the PANIC kills all your other sessions is annoying,
but in the scenarios where this is likely to happen you're trying to
stop them all anyway ...
