Systemd persistent change to service file

[Michael H <michael@xxxxxxxxxx>]

Hi All,

I had my database fall over earlier, Initially I thought it was due to a
change in the OS but the postgresql update overwrote my systemd service
file.

How can I create a file for my postgresql service that will not be
overwritten when updates are applied?

Am I correct in thinking it will be something like

vi /etc/systemd/system/postgresql.service.d/postgresql-limit-stack.conf
#with the contents:
.include /etc/systemd/system/multi-user.target.wants/postgresql.service
[Service]
LimitSTACK=17825792


thanks

Michael
