Hi John,
I dived into the issue in a panic, trying to fix something that was
completely unrelated. Turns out my service file was overwritten and lost
my stack setting. I've resolved it now with a drop-in snippet.
I like the look of the new features in postgresql but we are using
postgresql-server.x86_64 9.2.14-1.el7_1.
Thanks for the information,
Michael
