description	Consult Snowflake CREATE AGGREGATION POLICY parameter reference before generating any CREATE AGGREGATION POLICY DDL.

Before writing a CREATE AGGREGATION POLICY statement:

1. Read references/parameters.md to review all available parameters and their defaults.
2. For each parameter, decide whether the user's request implies a non-default value.
3. Include only the parameters that differ from the default or that the user explicitly requested.
4. Never use CREATE OR REPLACE — always use CREATE AGGREGATION POLICY IF NOT EXISTS.
5. The policy body must call either NO_AGGREGATION_CONSTRAINT() (unrestricted access) or AGGREGATION_CONSTRAINT(MIN_GROUP_SIZE => <n>) (requires aggregation with at least n rows per group).
6. Aggregation policies require Snowflake Enterprise Edition or higher; warn the user if their account edition is unknown.
7. The policy body cannot reference user-defined functions, tables, or views — only the built-in constraint functions are allowed.
