PostgreSQL

PostgreSQL in Illa is a database integration that allows you to connect and interact with a PostgreSQL database. PostgreSQL is a popular open-source relational database management system that is known for its stability, reliability, and powerful features.

With the PostgreSQL integration in Illa, you can query, insert, update, and delete data from a PostgreSQL database using SQL commands. You can also create custom SQL queries and run them within Illa action. This makes it easy to build data-driven applications and dashboards that display real-time data from a PostgreSQL database.
