I applied this bit.  I am unsure about the CREATE USER mentions that
appear just before each ALTER USER spot that got modified; should those
be updated to CREATE ROLE as well?  The only difference is that CREATE
USER adds the LOGIN privileges automatically, but the CREATE USER as as
skinny as ALTER USER.  Thoughts?
