Yeah, I like this for a different reason: just a couple days ago I was
comparing the postmaster's startup sequence to that used in standalone
mode (in postgres.c) and was momentarily confused because one had
reset_shared() where the other had CreateSharedMemoryAndSemaphores().
Looking in our git history, it seems that reset_shared() used to embed
slightly more knowledge, but it sure looks pretty pointless now.

Actually I think you chose the wrong place to move the comment to.
It applies to the initial postmaster start, because what it's pointing
out is that we'll probably choose the same IPC keys as any previous
run did. If we felt the need to enforce that during a crash restart,
we surely could do so directly.
Pushed after fiddling with the comments.
