Error: Permission Denied for Sequence Cities_Id_Seq Using Postgres

ERROR: permission denied for sequence cities_id_seq using Postgres

Since PostgreSQL 8.2 you have to use:

GRANT USAGE, SELECT ON SEQUENCE cities_id_seq TO www;

GRANT USAGE - For sequences, this privilege allows the use of the currval and nextval functions.

Also as pointed out by @epic_fil in the comments you can grant permissions to all the sequences in the schema with:

GRANT USAGE, SELECT ON ALL SEQUENCES IN SCHEMA public TO www;

Note: Don't forget to choose the database (\c <database_name>) before executing the privilege grant commands

Permission denied for relation

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.

GCloud Coud SQL Postgres: ERROR: permission denied for table table

The GRANT must be run by the owning user api.

Granting privileges on the database is not enough. To access a table, you must have privileges on the table itself as well as privileges on the schema that contains the table.

How can I insert records into Postgres with RLS when user has `grant all` perms and a loose policy

ERROR: permission denied for sequence report_files_id_seq

It looks to me like you need to grant your user permission to use the id sequence: report_files_id_seq

You should be able to do this with the following

GRANT USAGE, SELECT ON SEQUENCE report_files_id_seq TO testuser;

Or to bulk add all tables:

GRANT USAGE, SELECT ON ALL SEQUENCES IN SCHEMA <insert schema name here>

ALL is equivalent to USAGE, SELECT, UPDATE

Granted all privileges on my PostGres table, but still am getting a Permission denied error when attempting to insert/select

Your first command give you the ability to list table (you can just know that there are existing)

GRANT USAGE ON SCHEMA public TO myapp

Then you have to grant SELECT, INSERT, etc... to all the tables in the schema public

GRANT SELECT, UPDATE, INSERT, DELETE ON ALL TABLES IN SCHEMA public TO myapp

I recommand not giving all privileges to a specific app.

If you have sequences :

 GRANT SELECT, UPDATE, USAGE ON ALL SEQUENCES IN SCHEMA public to myapp

If you have functions :

GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA public TO myapp

Then your example will work.

But you still have to apply some command if you want futur created table to be able to be accessed :

ALTER DEFAULT PRIVILEGES IN SCHEMA public GRANT SELECT, UPDATE, INSERT, DELETE, TRIGGER ON TABLES TO myapp

Postgresql have a very weird mecanism it took me a while to understand it !

permission denied for schema api in tutorial

Yes, that's intended. authenticator doesn't have any privilege but to switch roles, as mentioned on https://postgrest.org/en/v9.0/auth.html#authentication-sequence.

So after connecting with authenticator through psql, you can do:

set local role web_anon;

Then you should be able to select * from api.todos.
