Wiresharking PostgreSQL - SELECT * FROM on Postgres behind the scenes

In this video we look behind the curtain of PostgresSQL and see how a single SELECT * FROM translate into the TCP stack. We will create a TCP postgres connection, authenticate, send the query, close the connection.

60+ Top PostgreSQL Tools

PostgreSQL, or Postgres for short, comes with many out-of-the-box features that make it very popular among developers and data engineers. Among the numerous benefits of implementing Postgres are that there are many approaches to take to scale your database horizontally or vertically — but that is a discussion for a whole different article. Postgres comes with plenty of add-ons and a strong community of developers behind it too for open-source support.

Aside from plugins that you can use to quickly add a variety of tools and resources to your Postgres suite, you can expand the many functionalities of your Postgres database system to help you take your use of Postgres to the next level.

PostgreSQL (Postgres) - Installation & Overview | SQL Tutorial | SQL for Beginners

Today we show you how to install PostgreSQL (aka “Postgres”). In addition to installing the database, we will install the pgAdmin GUI tool. Once Postgres and pgAdmin are installed, we will take a tour of the pgAdmin interface and learn how to create a new database.
