Seems like a couple of the comments could use updates:

This is no longer particularly sensible, since we're no longer making
any provision for wasted RmgrIds.  Perhaps rephrase as "RM_MAX_ID must
fit in RmgrId; widening that type will affect the XLOG file format."

Probably also a good idea to state explicitly that new entries should go
at the end to avoid moving the IDs of existing entries.

Works for me otherwise.
