It would be cleaner to make the array of LWLockIds part of ClogCtlData,
if you're going to do it that way. I have doubts that pushing all
LWLockIds into shared memory is a feasible solution, however.
Out of curiosity: have you actually tested any of this Windows code
you're proposing to commit? A lot of it looks to me like it's not
gonna work --- stuff is getting done too soon or too late. For
example, I don't see how a backend is going to read GUC variables
when it doesn't yet know where the data directory is.
