WHAT IT DOES

What pg_create_partitioned_table does on PostgreSQL MCP Server

RISK

Why pg_create_partitioned_table is rated Medium

This tool creates a new database object (partitioned table) with specified columns and constraints. This is a Write operation because it creates and persists new data structure, not a Destructive operation because the table creation itself is reversible via DROP TABLE.

From the tool's definition Tool creates a new table structure ('Create a partitioned table') which modifies the database schema irreversibly by adding a new table definition. While the table itself starts empty, the schema modification is a permanent write operation.
