privilege_not_granted means the current role lacks the privilege required to run the requested SQL statement.
privilege_not_granted in PostgreSQL appears when your role does not hold the needed privilege on a database object. Grant the missing right with GRANT <privilege> ON <object> TO <role>; to resolve the error.
PostgreSQL Error 1007
The privilege_not_granted error signals that PostgreSQL blocked an operation because the active role lacks a required privilege on the target object.
The server checks privileges at execution time. If the role has not been granted the specific right (SELECT, INSERT, UPDATE, DELETE, EXECUTE, USAGE, or CONNECT), PostgreSQL raises privilege_not_granted instead of performing the action.
Missing direct grants on the referenced table, view, sequence, function, or schema cause most occurrences.
Roles that rely only on default PUBLIC rights often hit this barrier.
Revoked or never-granted privileges after a schema change also trigger the error, especially during deployments or migrations.
Identify the required privilege with EXPLAIN or by reviewing the query. Grant that privilege to the role or a group role it belongs to.
Re-run the statement to confirm the fix.
For temporary needs, you can SET ROLE to a more privileged role, but permanent solutions should modify grants and follow least-privilege principles.
SELECT on analytics tables - GRANT SELECT ON analytics.* TO reporting_role; resolves read-only dashboard errors.
Function execution in APIs - GRANT EXECUTE ON FUNCTION api.upsert_user(integer,text) TO service_role; clears application exceptions.
Create group roles that mirror job functions, grant object privileges to groups, and add users to those groups.
Automate grants in migration scripts and validate with test roles during CI to catch privilege gaps before production.
insufficient_privilege (code 42501) is raised when the role explicitly lacks permission; fix it with the same GRANT approach.
undefined_table appears when the object does not exist rather than missing privilege; check schema search path and object names.
.
No. The table exists, but your role lacks the required privilege to access it.
Yes, if you own the object or hold grant options. Otherwise ask a superuser or owner to issue the GRANT.
It works but violates least-privilege. Grant only the specific privilege to reduce risk.
