Rename some shared memory initialization routines
To make them follow the usual naming convention whereFoobarShmemSize() calculates the amount of shared memory needed byFoobar subsystem, and FoobarShmemInit() performs the initialization.I didn't rename CreateLWLocks() and InitShmmeIndex(), because they area little special. They need to be called before any of the otherShmemInit() functions, because they set up the shared memorybookkeeping itself. I also didn't rename InitProcGlobal(), becauseunlike other Shmeminit functions, it's not called by individualbackends.Reviewed-by: Andreas KarlssonDiscussion:https://www.postgresql.org/message-id/c09694ff-2453-47e5-b26c-32a16cd75ce6@iki.fi
