Are you suggesting that because one of the backends did not exit
cleanly, that there is some problem?

Because the postmaster is resetting all shared memory at that point, I
am not sure that is the area.  I have been thinking about it, and my
guess is that one of the initialization functions (lock?) just appends
to the lock queue on restart, instead of clearing it first, and a
backend that does exec() starts out with clean global variables, which
they now do not.
