I have a problem granting permissions. The end result I'm looking for is:
Dustin and Pablo are data analysts. When either creates a table, the table must
be created outside of public, and both must be able to delete the table when
their work is finished. I would prefer that the tables they create be owned by
the dataanalysts role, but that's not required. They should have read-only
access to all tables in public. If a new table is created in public, they
should automatically receive read-only access.
Here's my implementation of the requirements:
-- Create both users
CREATE USER dustin WITH LOGIN;
CREATE USER pablo WITH LOGIN;
-- Both belong to the same role/group
CREATE USER dataanalysts WITH NOLOGIN;
GRANT dataanalysts TO pablo;
GRANT dataanalysts TO dustin;
-- Common schema for both
CREATE SCHEMA dataanalysts;
ALTER SCHEMA dataanalysts SET OWNER TO dataanalysts;
Wrong syntax:
ALTER SCHEMA dataanalysts OWNER TO dataanalysts;
No SET there.
-- Whenever a data analyst creates a table, prefer the dataanalysts schema
ALTER USER pablo SET search_path = dataanalysts, public;
ALTER USER dustin SET search_path = dataanalysts, public;
-- When pablo creates a table, allow any data analyst to query / update /
delete the table
ALTER DEFAULT PRIVILEGES FOR USER pablo IN SCHEMA dataanalysts GRANT ALL
PRIVILEGES ON TABLES TO dataanalysts;
-- When dustin creates a table, allow any data analyst to query / update /
delete the table
ALTER DEFAULT PRIVILEGES FOR USER dustin IN SCHEMA dataanalysts GRANT ALL
PRIVILEGES ON TABLES TO dataanalysts;
Here you change the default privileges for user pablo and dustin, but...
And the default privileges in this database are:
svanalytics_production=# \ddp
Default access privileges
Owner | Schema | Type | Access privileges
--------------+--------------+-------+-----------------------------------
dataanalysts | dataanalysts | table | dataanalysts=arwdDxt/dataanalysts
svanalytics | public | table | dataanalysts=r/svanalytics
I believe the first line means "if a data analyst creates a table, grant all privileges to
dataanalysts". The 2nd line means "when svanalytics creates a table in public, grant
select to dataanalysts".
Which are the defaults for pablo and dustin? If the ALTER DEFAULT
PRIVILEGES would have passed, you would see one line for each the two
users you created:
# \ddp
Default access privileges
Owner | Schema | Type | Access privileges
--------+--------------+-------+-----------------------------
dustin | dataanalysts | table | dataanalysts=arwdDxt/dustin
pablo | dataanalysts | table | dataanalysts=arwdDxt/pablo
This is the output I see after executing the DDL from above.
Did I miss anything? What did I do wrong? Why can't a dataanalyst view a
table's contents?
Not sure. Looks like ALTER DEFAULT PRIVILEGES didn't pass for some reason.
