Thanks, Dominik.

That solves that. There are a few new problems then. If I run it on a 
clean db, create-db works fine but in create-read-only-user I get:

An error occured: ERROR:  role "(my read-write user)" does not exist
ERROR:  role "(my read-write user)" does not exist
ERROR:  syntax error at or near "ALL"
LINE 1: GRANT SELECT ON ALL TABLES IN SCHEMA public TO "...

If I create the read-write user on my own first and then run create-db 
(ok), create-read-only-user gives:

An error occured: ERROR:  syntax error at or near "ALL"
LINE 1: GRANT SELECT ON ALL TABLES IN SCHEMA public TO "...
                         ^
ERROR:  syntax error at or near "DEFAULT"
LINE 1: ALTER DEFAULT PRIVILEGES FOR USER "ckanuser" IN SCHEMA publi...
               ^

By the way, in case this is helpful for the documentation: To get the 
environment right (paster on the PATH, access to db, write permission on 
the log file) I had to do this:

sudo su postgres -c  ". /home/ubuntu/pyenv/bin/activate; paster 
datastore ....

If I create the read-only user it throws about the user having write permission on the database. And after that I gave up because I couldn't figure out what I needed to revoke to get past that problem. :)
