📜 Tech Blog: Easy Guide to List all Tables in PostgreSQL information_schema

Hey there tech-savvy folks! 👋 Welcome back to our tech blog where we guide you through tricky problems and provide simple solutions. Are you trying to navigate the depths of PostgreSQL and need to list all the tables within the information_schema? Don't worry, we've got you covered! In this post, we'll address this common issue, provide easy solutions, and offer a compelling call-to-action. Let's dive right in! 🏊‍♀️💻

Understanding the Problem So, you're working with an empty database in PostgreSQL and want to explore the information_schema structure to find all the tables. This can be confusing at first, especially if you're new to PostgreSQL. But fear not, we'll break it down for you.

Solution 1: Using SQL Query One way to list all tables in the information_schema is by employing a SQL query. Here's an example you can try out in your database:

SELECT table_name
FROM information_schema.tables
WHERE table_schema = 'information_schema'

This query searches for all tables in the information_schema schema. It filters out any tables from other schemas, which could be useful if you're specifically interested in the information_schema tables.

Solution 2: Using psql Command-Line Tool If you're more comfortable with using command-line tools, PostgreSQL's psql is here to save the day! 🦸‍♂️ Simply run the following command in your terminal:

psql -c "SELECT table_name FROM information_schema.tables WHERE table_schema = 'information_schema'"

This command will give you the same result as the SQL query above, but without needing to enter the PostgreSQL shell.
