PostgreSQL systemd service is /bin/true

postgresql.service contents is

# systemd service for managing all PostgreSQL clusters on the system. This
# service is actually a systemd target, but we are using a service since
# targets cannot be reloaded.

[Unit]
Description=PostgreSQL RDBMS

Type=oneshot
ExecStart=/bin/true

I tried to start PostrgeSQL by service postgresql start and was surprised by postgresql.service contents, because it starts /bin/true

uname -a output:

Linux debian 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt25-2+deb8u3 (2016-07-02) x86_64 GNU/Linux

So my questions is: Why it happens, and how to fix it?


As indicated on the thread by @termcap, postgresql@{version}-main.service is the new service name.

So use systemctl {start|enable} [email protected].

Sensibly the postgresql.service should contain a friendly migration warning rather than /bin/true (work it out yourself).
