Hi,
I am having a few problems with access permissions.
When I create a new role with NOCREATEUSER and then create a database
for that role I can connect to the DB but when trying to create a db
object I will get the ERROR: permission denied for schema public.
Strangely though, if the role is created with CREATEUSERS I don't have
any problems.
So what arguments do you give to createuser and what does it show when
you add -e to the command?
Here is what I want to do:
1. Create a DBO role e.g. dbo_xxx NOCREATEDB NOCREATEUSER
2. Create a db mydb WITH OWNER db_xxx
3. REVOKE all connection rights from public
4. GRANT only rights to dbo_xxx
5. GRANT all create rights on mydb TO dbo_xxx ; allowing the user to
load the db schema
This is what I tried
Who are doing the below as?
REVOKE ALL ON SCHEMA public FROM PUBLIC;
CREATE USER dbo_xxx WITH PASSWORD 'mypass' NOCREATEDB NOCREATEUSER;
CREATE DATABASE my_db WITH OWNER dbo_xxx ENCODING 'UTF8';
REVOKE CONNECT ON DATABASE my_db FROM PUBLIC;
GRANT CONNECT ON DATABASE my_db TO dbo_xxx;
GRANT ALL PRIVILEGES ON DATABASE my_db TO dbo_xxx;
Well the above only GRANTs on the database not objects within it. For
more information see:
http://www.postgresql.org/docs/9.4/interactive/sql-grant.html
For databases that means CREATE and CONNECT
Since you already REVOKed ALL on schema public FROM PUBLIC and did not
GRANT SCHEMA privileges to dbo_xxx on schema public, I am pretty sure
that is where your problem is. To get a clearer idea of what is going on
can you show:
\l my_db
and in my_db
\dn+ public
-- After schema is loaded
CREATE USER read_only WITH PASSWORD 'mypass' NOCREATEDB NOCREATEUSER;
REVOKE ALL ON ALL TABLES IN SCHEMA public FROM PUBLIC ;
GRANT SELECT ON ALL TABLES IN SCHEMA public TO read_only ;
But i end up with permission denied errors.
Anyone having a suggestion how to get this to work? Did I mess up
permissions in public schema?
Any help and suggestion is greatly appreciated.
