When I switched on my computer today the postgresql service suddenly wouldn't start. Its been working fine since I installed. It runs fine by running the command below as the user postgres
/usr/lib/postgresql/9.5/bin/pg_ctl -D /var/lib/postgresql/9.5/main -l logfile start
But it just won't start as a service anymore and there is zero logging in postgresql or syslog. How can I troubleshoot this without any logging?
