Thanks for adding this documentation!  Unfortunately, the cfbot can't apply a
patchset split in multiple emails, so for now you only get coverage for this
new readme file, as this is what's being tested on the CI:
https://github.com/postgresql-cfbot/postgresql/commit/f8f12ce29344bc7c72665c334b5eb40cee22becd

Could you send the full patchset each time you make a modification?  For now
I'm simply attaching 0001, 0002 and 0003 to make sure that the cfbot will pick
all current patches on its next run.
