What You Master

The Complete PostgreSQL Skill Set

From JSONB and window functions to PL/pgSQL, partitioning, and cloud deployment on AWS, GCP, and Supabase.

🐘

Advanced SQL & JSONB — Beyond Relational

Write complex analytical queries with window functions (ROW_NUMBER, RANK, LAG/LEAD), recursive CTEs, and GROUPING SETS. Store and query semi-structured data natively with JSONB operators (->>, @>, ?). Use EXPLAIN ANALYZE to understand and optimise query plans for production performance.

⚙️

PL/pgSQL Functions

Write server-side procedures and functions in PL/pgSQL. Add triggers, exception handling, and custom aggregates.

☁️

Cloud & Modern Stack

Deploy on AWS RDS, Google Cloud SQL, Supabase, or Neon. The backbone of every modern SaaS application.

🔒

ACID, Security & MVCC

Full ACID compliance via MVCC — multiple users, zero blocking. Row-level security, SSL/TLS, roles & privileges for enterprise use.
