Course Topics
Introduction to PostgreSQL
What PostgreSQL is, why it’s popular, and when to choose it
Installing PostgreSQL & Basic Setup
Install Postgres locally or with Docker and create your first database
psql & Basic Queries (CRUD)
Learn the PostgreSQL CLI and core SQL operations
Data Modeling & Schema Design
Design tables, keys, and constraints that keep data correct
Data Types & JSONB
Use Postgres types effectively, including JSONB for flexible data
Joins & Relationships
Combine tables to answer real questions about your data
Indexing & Performance
Speed up queries with the right indexes and EXPLAIN
Transactions & Concurrency
Keep data consistent with ACID and isolation levels
Views, Functions & Extensions
Encapsulate logic and extend Postgres capabilities
Backup, Security & Maintenance
Protect your data and keep Postgres healthy
PostgreSQL Indexing Strategies
Master B-tree, GIN, GiST, BRIN indexes, composite and partial indexes, and EXPLAIN ANALYZE for PostgreSQL query optimization.
Working with JSONB in PostgreSQL
Master JSONB operators, indexing, aggregation, and know when to use JSONB vs normalized relational tables.
PostgreSQL Window Functions
Use ROW_NUMBER, RANK, LAG, LEAD, and window frames for running totals, moving averages, and analytics queries.
Common Table Expressions & Recursive Queries
Write readable CTEs and recursive queries for hierarchies, trees, and graph traversal in PostgreSQL.
Transactions & Concurrency Control
Master ACID, isolation levels, locking strategies, deadlock prevention, and job queues with FOR UPDATE SKIP LOCKED.
Table Partitioning in PostgreSQL
Use range, list, and hash partitioning for large tables with declarative syntax, partition pruning, and maintenance.
Full-Text Search in PostgreSQL
Build powerful search with tsvector, tsquery, GIN indexes, ranking, and phrase search without Elasticsearch.
Functions & Stored Procedures
Write PL/pgSQL functions, triggers, error handling, and understand security definer vs invoker in PostgreSQL.
PostgreSQL Performance Tuning
Optimize PostgreSQL with EXPLAIN ANALYZE, configuration tuning, connection pooling, and VACUUM strategies.
PostgreSQL Replication & High Availability
Set up streaming and logical replication, read replicas, failover with Patroni, and WAL archiving in PostgreSQL.
PostgreSQL Security Best Practices
Secure PostgreSQL with roles, GRANT/REVOKE, Row Level Security, SSL, pg_hba.conf, and audit logging.
Database Migrations & Schema Versioning
Manage PostgreSQL schema changes with migration tools, zero-downtime strategies, and safe rollback practices.
