 This Gemini CLI extension provides a set of tools to interact with [PostgreSQL](https://www.postgresql.org/docs/) instances. It allows you to manage your databases, execute queries, and explore schemas directly from the [Gemini CLI](https://google-gemini.github.io/gemini-cli/), using natural language prompts.

 ## Why Use the Postgres Extension?
 
-*   **Natural Language Management:** Stop wrestling with complex commands. Explore schemas and query data by describing what you want in plain English.
-*   **Seamless Workflow:** Stay in your CLI. No need to constantly switch contexts to the GCP console for common database tasks.
-*   **Code Generation:** Accelerate development by asking Gemini to generate data classes and other code snippets based on your table schemas.
