Description

In zero mode, non-standard DDL syntax for table creation (e.g., create table fork, create table like) currently bypasses the configured table limit. These operations need to be restricted to enforce the table limit correctly.

Impact

Without restriction, users can circumvent the intended table limit, potentially leading to resource exhaustion or performance degradation in zero mode deployments.
