Does it include security best practices?

Yes, it covers Row-Level Security (RLS) and the correct application of PK, FK, and UNIQUE constraints to ensure data integrity and security.

Can it help improve database performance?

Absolutely. It includes rules for indexing access paths, partitioning large tables, and using appropriate table types like UNLOGGED for staging data.

Is this skill suitable for high-scale applications?

Yes, it includes advanced strategies for partitioning (Range, List, Hash) and insert-heavy workload optimizations suitable for enterprise scale.

Why does it prefer TEXT over VARCHAR(n)?

PostgreSQL handles both similarly under the hood; using TEXT with CHECK constraints provides more flexibility for schema evolution without performance penalties.

Does this skill support advanced PostgreSQL types?

Yes, it provides specific guidance on JSONB, Arrays, Range types, Network types, and Vector types for AI similarity searches.
