How does this skill improve PostgreSQL performance?

It enforces specific indexing patterns, such as manual FK indexing and the use of GIN/GiST for complex data, while recommending performance-tuned settings like fillfactor for update-heavy tables.

Does it cover database security?

It provides guidance on implementing Row-Level Security (RLS) policies to handle access control directly at the database layer.

What data types does this skill recommend avoiding?

It explicitly advises against using serial, varchar(n), char(n), and timestamp without time zone, suggesting modern alternatives like generated identity columns and text/timestamptz.

Does it support the latest PostgreSQL features?

Yes, it includes modern patterns like 'NULLS NOT DISTINCT' (PG15+), identity columns, and pgvector support for AI applications.

Can it help with database partitioning?

Yes, it provides implementation patterns for Range, List, and Hash declarative partitioning to manage tables exceeding 100 million rows.
