Symptoms

A statement failed with SQLSTATE 0LP01 (invalid_grant_operation), reported at severity ERROR. This is a Invalid Grantor condition: PostgreSQL emits the message cannot use IN SCHEMA clause when using GRANT/REVOKE ON SCHEMAS.

• The client receives SQLSTATE 0LP01 (invalid grant operation).
• The operation is rejected at ERROR level; the statement does not complete.

What the server log shows

ERROR:  cannot use IN SCHEMA clause when using GRANT/REVOKE ON SCHEMAS

Why PostgreSQL raises this

PostgreSQL raises this error from the area indicated by its SQLSTATE class. The condition name pinpoints the specific rule that was violated.

As described in PostgreSQL’s Appendix A PostgreSQL Error Codes, SQLSTATE 0LP01 carries the condition name invalid_grant_operation in class Invalid Grantor. (Paraphrased — see the linked reference for the exact wording.)

Common causes

• The operation violated the rule named by this SQLSTATE condition.
• An input, object, or state did not satisfy a precondition.

How to fix it

1. Use the SQLSTATE condition name to identify the exact rule.
2. Correct the offending input, object, or state and retry.
3. See the linked full SQLSTATE reference for detailed guidance.

Version applicability

This message text is present in PostgreSQL 15, 16, 17.
