RISK

Why pg_partman_create_parent is rated Medium

This tool creates a new partition set in PostgreSQL using the pg_partman extension. Creating partition sets is a Write operation as it establishes new database structures. Severity is high because misconfiguring a partition set can have significant impacts on database performance and data organization, and it may be difficult to cleanly undo complex partitioning schemes.
