postgresql systemd service fails to start only on boot but notmanually - Mailing list pgsql-general

Hello everyone,

I'm having trouble with my PostgreSQL Systemd service and I wonder
whether this is a problem with the software or some problem with the
packaging or build.

My server fails to start PostgreSQL only on boot, if I restart it
manually afterwards it doesn't have any problem starting. Here is the
log extracted from the journal:

```

```

Any Ideas? I'd really like to fix this since now after every reboot I have to
remember to manually restart it.

Thanks.
