To optimize slow PostgreSQL queries, you should use EXPLAIN to analyze query plans, implement proper indexing strategies, and apply schema design best practices to reduce execution time and improve database performance.

The best way to monitor PostgreSQL performance is by utilizing EXPLAIN for query execution plans, pg_stat_statements for tracking query statistics, and VACUUM for managing storage bloat to ensure efficient database operations.

Row-Level Security (RLS) in PostgreSQL works by restricting data access at the row level based on user roles, allowing you to implement the principle of least privilege and ensure secure, compliant data access directly within the database schema.

You need to use VACUUM to reclaim storage from dead tuples and EXPLAIN to diagnose slow query execution plans when your PostgreSQL database experiences performance degradation or inefficient query performance during routine database tuning.

Yes, you need prior familiarity with PostgreSQL and common optimization techniques, such as using EXPLAIN, VACUUM, and RLS policies, to effectively apply these advanced performance optimization and database tuning guidelines.
