{/* MANUAL-CONTENT-START:intro */}
The [PostgreSQL](https://www.postgresql.org/) tool enables you to connect to any PostgreSQL database and perform a wide range of database operations directly within your agentic workflows. With secure connection handling and flexible configuration, you can easily manage and interact with your data.

With the PostgreSQL tool, you can:

- **Query data**: Execute SELECT queries to retrieve data from your PostgreSQL tables using the `postgresql_query` operation.
- **Insert records**: Add new rows to your tables with the `postgresql_insert` operation by specifying the table and data to insert.
- **Update records**: Modify existing data in your tables using the `postgresql_update` operation, providing the table, new data, and WHERE conditions.
- **Delete records**: Remove rows from your tables with the `postgresql_delete` operation, specifying the table and WHERE conditions.
- **Execute raw SQL**: Run any custom SQL command using the `postgresql_execute` operation for advanced use cases.

The PostgreSQL tool is ideal for scenarios where your agents need to interact with structured data—such as automating reporting, syncing data between systems, or powering data-driven workflows. It streamlines database access, making it easy to read, write, and manage your PostgreSQL data programmatically.
