I tried to run simple sql command:
select * from site_adzone;
and I got this error
ERROR: permission denied for relation site_adzone
What could be the problem here?
I tried also to do select for other tables and got same issue. I also tried to do this:
GRANT ALL PRIVILEGES ON DATABASE jerry to tom;
but I got this response from console
WARNING: no privileges were granted for "jerry"
Do you have some idea what can be wrong?
回答1:
GRANT on the database is not what you need. Grant on the tables directly.
Granting privileges on the database mostly is used to grant or revoke connect privileges. This allows you to specify who may do stuff in the database if they have sufficient other permissions.
You want instead:
GRANT ALL PRIVILEGES ON TABLE side_adzone TO jerry;
This will take care of this issue.

Posting Ron E answer for grant privileges on all tables as it might be useful to others.
GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO jerry;

Connect to the right database first, then run:
GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO jerry;
回答4:
To grant permissions for existing tables use:
GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA TO
To specify default permissions that will be applied to future tables use:
ALTER DEFAULT PRIVILEGES IN SCHEMA GRANT ON TABLES TO ;
e.g.
ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT, INSERT, UPDATE, DELETE ON TABLES TO admin;
If you use SERIAL
or BIGSERIAL
columns then you will probably want to do the same for SEQUENCES
, or else your INSERT
will fail (Postgres 10's IDENTITY
doesn't suffer from that problem, and is recommended over the SERIAL
types), i.e.
ALTER DEFAULT PRIVILEGES IN SCHEMA GRANT ALL ON SEQUENCES TO ;
