Amazon RDS - Postgresql role cannot access tables

Question

created a postgresql instance on AWS with the username ziggy. I restored a database to that instance. however I cannot even select any of the tables

select * FROM mac_childcare_parcels

gives me ERROR: permission denied for relation mac_childcare_parcels ********** Error **********

the owner of that table belongs to the postgres login.

so i tried running this: grant all privileges on all tables in schema public to ziggy but since I am not a superuser I cannot give myself privileges so that throws a permissions error. what do I have to do to get access to the tables?

this does not work either

grant select on mac_childcare_parcels to ziggy

this query returns successful but does not let the login ziggy access the tables

GRANT USAGE ON SCHEMA public TO ziggy;

Answer 1

First login with superuser and provide all rds superuser access to the newly created user using a command like below

GRANT rds_superuser TO ziggy;

replace rds_superuser with your rds superuser.

Answer 2

您还需要在 SCHEMA 上授予使用权，例如

GRANT USAGE ON SCHEMA public TO ziggy;

Answer 3

The superuser access is needed to run the access level queries. But as you said that access is not present then i would say copy the replica of the db which you have restored from backup and grant yourself as superuser. then provide all needed access to any users.
