Well, this host has a problem, for what looks like a kernel issue, I
guess.. This is repeatable across all the branches, randomly, with
various errors with the POSIX DSM implementation:
# [63cf68b7.5e5a:1] ERROR: could not open shared memory segment "/PostgreSQL.543738922": No such file or directory
# [63cf68b7.5e58:6] ERROR: could not open shared memory segment "/PostgreSQL.543738922": No such file or directory

dynamic_shared_memory_type should be using posix in this case.
Switching to mmap may help, perhaps.. I need to test it.
Anyway, sorry for the noise on this one.
