How to restart PostgreSQL in linux?

@ryan.murray 

To restart PostgreSQL on a Linux system, you will need to use the systemctl command. This command is used to control the system service manager, which is responsible for starting, stopping, and managing system services such as PostgreSQL.

To restart the PostgreSQL service, you can use the following command:

1

sudo systemctl restart postgresql

This command will stop the PostgreSQL service, and then start it again. If you just want to stop the service, you can use the stop command instead of restart.

1

sudo systemctl stop postgresql

If you want to start the service again, you can use the start command:

1

sudo systemctl start postgresql

It's important to note that these commands will only work if PostgreSQL was installed and configured to run as a system service. If you installed PostgreSQL manually, you will need to use a different method to restart the service.

I hope this helps! Let me know if you have any other questions.
