First off, I LOVE webmin/virtualmin, been using it only a week, but I'm hooked. Amazing work!
Only issue has stumped me is postgresql, I have disabled it from startup, no virtual servers are using it. (No virtual servers using the feature PostgreSQL database were found.)
I took it out of the monitor, yet it as soon as I stop it, it starts itself back up again.
I am not sure what else I can do... looking for how to find out where it is starting and how to stop it...
I removed it entirely, but then I got an error on the system information page, so I put it back on.
