PostgreSQL Production Labs · For Experienced DBAs
You Are Not Learning
You Are Not Learning
a New Database.
You Are Translating Your Skills.
If you have years of experience managing Oracle, SQL Server, or MySQL — your core DBA knowledge is already transferable. The tools change. The responsibilities don't.
❌ The wrong question
"How do I learn PostgreSQL?"
- Feels like starting over from zero
- Makes 10 years of DBA experience feel irrelevant
- Leads to memorizing commands instead of understanding responsibilities
- Creates unnecessary anxiety for experienced engineers
✅ The right question
"How does PostgreSQL do what I already do?"
- Builds on everything you already know
- Makes your existing experience the foundation
- Maps familiar responsibilities to PostgreSQL equivalents
- Turns a steep learning curve into a vocabulary shift
How Naresh teaches this in the live demo
Don't ask me "How do I learn PostgreSQL?"
Ask me this instead:
"In Oracle, I perform UNDO tablespace management every quarter. Do we have an equivalent in PostgreSQL?"
MVCC handles it →
"We conduct DR drills regularly. How is that done in PostgreSQL?"
Switchover to Standby →
"We use Always On Availability Groups in SQL Server. What's the PostgreSQL equivalent?"
Patroni + Streaming Replication →
"MySQL has the InnoDB storage engine. What is the corresponding concept in PostgreSQL?"
PostgreSQL's own storage engine →
"I take RMAN backups every night. What tools do we use here?"
pgBackRest / pg_basebackup →
"I monitor Data Guard lag. How do we monitor replication lag in PostgreSQL?"
pg_stat_replication →
"I patch Oracle every quarter. What's the PostgreSQL upgrade process?"
pg_upgrade →
Almost every responsibility you perform as a DBA has an equivalent workflow in PostgreSQL. Once you understand that mapping, learning PostgreSQL becomes much easier.
You are not learning databases from scratch. You are learning how to perform the same responsibilities on a different platform.

Your PostgreSQL Learning Strategy
Three Steps.
Three Steps.
That's the Entire Method.
1
Write down everything you do in your current job
Your backup schedule. Your DR process. Your weekly maintenance tasks. Your monitoring checks.
Every operational responsibility you perform, regardless of the database.
2
Ask one question for each item
"How does PostgreSQL do this?"
Not "what are PostgreSQL features?" — your specific responsibility, mapped to PostgreSQL's equivalent.
Not "what are PostgreSQL features?" — your specific responsibility, mapped to PostgreSQL's equivalent.
Examples from the live demo
- In Oracle, I perform UNDO tablespace management every quarter. Do we have an equivalent in PostgreSQL?
- We conduct DR drills regularly. How is that done in PostgreSQL?
- We use Always On Availability Groups. What's the PostgreSQL equivalent?
- MySQL has the InnoDB storage engine. What is the corresponding concept in PostgreSQL?
- I take RMAN backups. What tools do we use here?
- I monitor Data Guard lag. How do we monitor replication lag in PostgreSQL?
- I patch Oracle every quarter. What's the PostgreSQL upgrade process?

You've already learned most of PostgreSQL administration
If you can answer that question for every responsibility you already perform,
you understand PostgreSQL operations.
What remains is tool familiarity — and that comes fast with hands-on practice.
Most instructors teach PostgreSQL chapter by chapter — Architecture, then Installation, then Configuration, then Security.
This course teaches it differently.
What do you already know? Let's translate it.
Someone with 10 years of Oracle experience is not a beginner. They are a DBA who needs to learn PostgreSQL's terminology, tools, and operational approach. That is a very different starting point — and it means you will learn much faster than you think.
Bring your real responsibilities.
We'll map them to PostgreSQL.
Ask anything from your current job. If you do it in Oracle, SQL Server, or MySQL —
there is a PostgreSQL way to do it. Let's find it together.
