command for show the table and columns and values

To view a PostgreSQL table in Visual Studio Code (VSCode), you can use the PostgreSQL extension. Here's a step-by-step guide:

1. Install the PostgreSQL extension for VSCode from the Visual Studio Marketplace.
2. Open VSCode and connect to your PostgreSQL database by opening the Command Palette (Ctrl + Shift + P) and selecting 'PostgreSQL: New Query'.
3. Create a new connection profile by following the prompts to enter your PostgreSQL instance's hostname, database, username, and password.
4. Once connected, you can write a query to view the table data. For example, to view all data from a table named Books, you would write:

   SELECT * FROM Books;

1. Execute the query by right-clicking and selecting 'Execute Query'. The results will be displayed in a new tab within VSCode.
