I have Postgresql 9.3 and 9.4 installed on my Linux Mint machine. How can I restart postgresql 9.4? A method to restart both versions together is also fine.
回答1:
Try this as root (maybe you can use sudo or su):
/etc/init.d/postgresql restart
Without any argument the script also gives you a hint on how to restart a specific version
[Uqbar@Feynman ~] /etc/init.d/postgresql
Usage: /etc/init.d/postgresql {start|stop|restart|reload|force-reload|status} [version ...]
Similarly, in case you have it, you can also use the service tool:
[Uqbar@Feynman ~] service postgresql
Usage: /etc/init.d/postgresql {start|stop|restart|reload|force reload|status} [version ...]
Please, pay attention to the optional [version ...] trailing argument.
That's meant to allow you, the user, to act on a specific version, in case you were running multiple ones. So you can restart version X while keeping version Y and Z untouched and running.
Finally, in case you are running systemd, then you can use systemctl like this:
[support@Feynman ~] systemctl status postgresql
● postgresql.service - PostgreSQL database server
Loaded: loaded (/usr/lib/systemd/system/postgresql.service; enabled; vendor preset: disabled)
Active: active (running) since Wed 2017-11-14 12:33:35 CET; 7min ago
...
You can replace status with stop, start or restart as well as other actions. Please refer to the documentation for full details. Unluckily there seems to be no way to operate on multiple versions of Postgresql with this tool.
Finally Keep in mind that root permissions may be needed for non-informative tasks as in the other cases seen earlier.

You can also restart postgresql by using this command, should work on both the versions :
sudo service postgresql start
