What is PostgresDB 2F004: Reading SQL Data Not Permitted

When encountering the error 2F004: Reading SQL Data Not Permitted from a Postgres database, the immediate action to take is to check the permissions of the user encountering this error.

Connect to your Postgres database:Open your terminal or command prompt.Use the following command to connect to your Postgres database, replacing your_database with the name of your database, and your_username with your username:psql -d your_database -U your_usernameCheck the current role's permissions:Run the following SQL query to check the permissions of the current user:SELECT * FROM information_schema.role_table_grants WHERE grantee = CURRENT_USER;Check if the role has the necessary SELECT permission on the table:If you know the specific table you're trying to access, replace your_table_name with the name of your table in the query below to verify permissions:SELECT grantee, privilege_typeFROM information_schema.role_table_grantsWHERE table_name = 'your_table_name' AND grantee = CURRENT_USER;Identify if the role is part of any group with the required permissions:Sometimes, the direct permissions might not be granted, but the user could be part of a role/group that has the necessary permissions. Check this with:SELECT rolname FROM pg_roles WHERE oid = ANY (current_user::regrole::oid <<| array(select oid from pg_roles));Check for Row-Level Security Policies (if applicable):If the table has Row-Level Security (RLS) enabled, check the policies that might restrict data access:SELECT policyname, cmd, roles, qual, with_checkFROM pg_policiesWHERE schemaname = 'your_schema_name' AND tablename = 'your_table_name';Replace your_schema_name with the schema name of your table, and your_table_name with the name of your table.

By following these steps, you should be able to identify why the error "Reading SQL Data Not Permitted" is occurring. If it's due to missing permissions, you may need to contact whoever has administrative access to grant the necessary permissions. If you have the necessary privileges, you can grant select permission to the user for the table in question using:

GRANT SELECT ON your_table_name TO your_username;

Replace your_table_name with the name of your table and your_username with the name of the user needing access.
