Question

I just installed PostgreSQL 8.4.7 with EnterpriseDB’s one-click installer on Mac OS 10.6.6. I would like to reproduce the following command from Ubuntu:

sudo -u postgres createuser --createdb --no-createrole --pwprompt --no-superuser [username]

but I’m unsure how to do this. An early version using dscl and taking care of the pwprompt option is

dscl -p localhost -create /Users/[username]

but I’m at a loss of how to apply the createdb, no-createrole and no-superuser options.

Any input would be greatly appreciated!

Answer 1

createuser is about creating users inside the postgresql database, not (directly) to do with your local system users, which is what dscl seems to be for.

If your one-click install didn’t include the createuser commands etc., don’t worry: they are just wrappers for invoking administrative SQL commands and their functionality can be performed from psql anyway. For example, the createuser system command maps to the CREATE USER SQL command: http://www.postgresql.org/docs/9.0/static/sql-createuser.html

If you can connect to your newly-installed postgres database using psql (e.g. psql -U postgres postgres) then you don’t need the other commands.
