While testing this, I ran into another semi-related issue:
shmem_exit_inprogress isn't ever being cleared in the postmaster, which
means that if you ever have a crash-restart, any attempt to do a
rollback in a procedure will then crash or get some other form of
corruption again every time until you manually restart the cluster.
