Init.d script for Postgresql 9.6 on ubuntu 14 is not working after reboot

I upgraded postgres from default repo, didnt use any other. Later I found that I had installed already postgres 10, so when I upgraded my pgcluster to 10 it started to work. But later, I forgot to remove old postgres install files and after their upgrade, it is not working again. I did test like 10 minutes ago, service postgresql stop/start did nothing, I have to run it manually with pg_ctl command

this is my init script

#!/bin/sh
set -e

The version of Postgresql shipped on the Rails One-Click application is the default version from the Ubuntu repositories. No custom init script is used. By default Ubuntu 14.04 ships Postgresql 9.3. Have you installed installed a new version from a third-party repository? Can you share the init script and any relevant logs?
