To activate the PostgreSQL service, you can follow these steps:

1. Start the PostgreSQL Service

Run the following command to start the PostgreSQL service:

bash:

sudo systemctl start postgresql

2. Enable PostgreSQL to Start on Boot

To ensure PostgreSQL starts automatically at system boot, enable it using:

bash:

sudo systemctl enable postgresql

3. Check the Service Status

Verify that the service is active and running:

bash:

sudo systemctl status postgresql

The output should show that the service is active (running).

Troubleshooting

• If the service does not start, check the logs for detailed information:

bash:

sudo journalctl -u postgresql

• Ensure PostgreSQL is installed correctly and the configuration files are not corrupted. Let me know if you encounter any specific issues!
