PostgreSQL is a powerful, open source object-relational database system with over 35 years of active development that has earned it a stron reputation for reliability, feature robustness, and performance.

The CREATE DATABASE command has a number of options, as you can see in the documentation.

Also, when you restore a database, PostgreSQL uses template0 to start that process (I’ll explain how and why once I learn).Īnd what about that postgres database? Well, that’s a default built into PostgreSQL so that tools always connect to a default database. What’s that? Well, in the event you completely mess up template1, template0 acts as a baseline. However, there’s more going on in PostgreSQL. You can add objects to template1, and then they will automatically exist in any other new database you create. The table template1 operates very similarly to model. In PostgreSQL, the same thing happens, but the database is called template1. In SQL Server, you have a system database called model used as a template when you create a new database. Since I know SQL Server, I’m going to compare what’s going on here, to what’s going on there. The command to create a database is quite simple: I don’t want to document every single possible method, so I had to pick one.

I’m old, and I’m just more comfortable working on code within a dedicated coding tool as opposed to simply running it from the command line.

For example, it plugs in very nicely to GitHub, so you can easily keep the code as you develop it up on GitHub ( go here if you want to see my VERY basic PostgreSQL code: ).

I’m going to focus there, working primarily within Azure Data Studio (ADS). Finally, the SQL commands are available once you’re connected to PostgreSQL. You can do everything from a command line or use a graphical user interface (GUI) that lets you work with PostgreSQL. I could then back them up.Īs with any data management system, there are many ways to get this done. I needed to create a database and a couple of tables. However, I realized I had another thing I needed to do before I could begin learning – and teaching - backups. Now, what to do with it? In the first article in this series, I said I would start by learning about backups. You have an instance of PostgreSQL running locally (or you’re connected to the cloud).
