Description of problem: It appears that zabbix-server-pgsql doesn't start properly. I imagine this is because systemd hasn't yet started postgresql and zabbix startup stuff isn't configured properly to wait on postgresql. Zabbix can be started manually AFTER boot, but doesn't start automatically. Version-Release number of selected component (if applicable): 1.8.5-3
As a workaround for mysql, I copied /lib/systemd/system/mysqld.service to /etc/systemd/system/ and added: Before=zabbix-server.service The same could be done with postgresql.service.
