I think we should redesign the shared memory API (and even more so the
semaphore API), not just put a wrapper layer on it. A lot of the
internal API is unnecessarily dependent on SysV shmem/sem behavior.
Note however that there are some things you will break if you are not
very careful. We are depending on shmem/sem behavior to catch a number
of multiple-postmaster conflict situations. If there's not a more or
less SysV-ish kernel underneath us, those situations will have to be
rethought and some other interlock invented.
In short, I want to see a design review first, not a bunch of
off-the-cuff commits.
