On several servers I've seen failures to start postgres after VM reboot:

{quote}# systemctl status postgresql
● postgresql.service - PostgreSQL database server
   Loaded: loaded (/etc/systemd/system/postgresql.service; enabled; vendor preset: disabled)
   Active: failed (Result: exit-code) since Tue 2016-07-12 15:40:46 UTC; 15min ago

Jul 12 15:40:45 el7-vm05 systemd[1]: Starting PostgreSQL database server...

Jul 12 15:40:46 el7-vm05 pg_ctl[6237]: pg_ctl: could not start server
Jul 12 15:40:46 el7-vm05 systemd[1]: postgresql.service: control process exited, code=exited status=1
Jul 12 15:40:46 el7-vm05 systemd[1]: Failed to start PostgreSQL database server.
Jul 12 15:40:46 el7-vm05 systemd[1]: Unit postgresql.service entered failed state.
Jul 12 15:40:46 el7-vm05 systemd[1]: postgresql.service failed.{quote}

the temporary directory does not exist:

{quote}# ls -l /var/run/postgresql/
ls: cannot access /var/run/postgresql/: No such file or directory
# rpm -V postgresql-server
missing     /var/run/postgresql
# rpm -q postgresql-server
postgresql-server-9.2.15-1.el7_2.x86_64{quote}

It is defined in systemd configs however:
{quote}# cat /usr/lib/tmpfiles.d/postgresql.conf
d /var/run/postgresql 0755 postgres postgres -
{quote}

We need to identify why systemd does not create this directory as it requires manual work to bring such VM up.
