Re: [Proposal] Fully WAL logged CREATE DATABASE - No Checkpoints

You may also need to add documentation to app-createdb.sgml. Currently
you have just added to create_database.sgml. Also, I had a quick look

and they seemed fine to me although I haven't put much emphasis on the
comments and other cosmetic stuff.
