Everything you need to know about the PostgreSQL DBA Mastery Course
General Questions
Who is this course for?
This course is designed for mid-level DBAs (3-7 years) wanting production mastery, senior DBAs building for cloud-native, SREs owning the database stack, and Oracle DBAs migrating to PostgreSQL. Three career tracks: Track 1 Core Operations (₹20K), Track 2 Production DBRE (₹35K), Track 3 Staff DBRE Mastery (₹55K).
What prerequisites do I need?
Basic SQL knowledge (SELECT, INSERT, UPDATE) is required. Linux command line familiarity is helpful but not required—we provide Docker environments. All 3 tracks are cumulative—Track 2 includes Track 1, Track 3 includes both. 6 bonus prerequisite modules are included free.
How long does it take to complete?
Track 1 Core Operations: 4-6 weeks (study 4 projects)
Track 2 Production DBRE: 12 weeks (Track 1 + build SampleBank)
Track 3 Staff DBRE Mastery: 22 weeks (Track 2 + advanced modules)
Part-time (1-2 hours/day): 6-12 months
Track 2 Production DBRE: 12 weeks (Track 1 + build SampleBank)
Track 3 Staff DBRE Mastery: 22 weeks (Track 2 + advanced modules)
Part-time (1-2 hours/day): 6-12 months
Is this course self-paced?
Yes, completely self-paced with lifetime access. You can start, pause, and resume anytime. All future updates are included at no extra cost.
Course Content
What is SampleBank?
The course uses 5 real projects. In Track 1, you do hands-on practicals with ProductionDB (install, configure, backup, HA, failover, migrate, deploy to AWS) and study 3 BankForge production codebases (Core, DBA-Operations, AI). In Track 2, you build SampleBank v4.5 from scratch—a complete multi-tenant banking app with UPI, NEFT, loans, and compliance features. Not toy examples, real production work.
What version of PostgreSQL is covered?
We focus on PostgreSQL 17 and 18, but concepts apply to versions 12+. The upgrade module specifically covers migrating between major versions (16→18, etc.).
Are all three cloud platforms covered equally?
Yes. AWS RDS is covered in Track 1 (Module 7), while Azure Database for PostgreSQL (Module 32) and GCP Cloud SQL (Module 33) are bonus specialist modules. Each has dedicated labs, Terraform scripts, and production checklists.
What’s special about the Kubernetes module?
Module 22 is the most comprehensive Kubernetes PostgreSQL training available—38 hands-on labs covering: Zalando Postgres Operator, Bitnami Helm charts, storage management, networking (PgBouncer, NetworkPolicies), security (TLS, secrets), backup (WAL-G, Velero), observability, and troubleshooting.
Do I get the scripts and code?
Absolutely. You get 5,100+ files including 125 production automation scripts, Terraform configurations, Docker Compose files, Python data generators, Grafana dashboards, and the complete SampleBank application. Plus bonus modules covering 12 trending PostgreSQL extensions and complete migration labs for MySQL, SQL Server, and Oracle to PostgreSQL (with pgloader, ora2pg, sqlserver2pgsql). All copy-paste ready for your own projects.

Do I need cloud accounts?
Most labs run locally with Docker. For cloud-specific modules (AWS RDS, Azure, GCP), free tier accounts work for all labs. We provide cost estimates and cleanup scripts to avoid charges.
Is Docker required?
Yes, Docker Desktop (or Docker Engine on Linux) is required for all labs. This ensures consistent environments regardless of your OS. We provide Docker Compose files for every technology stack.
