PostgreSQL won't start on Mint /var/run/postgresql/.s.PGSQL.5432

hack.txt

After installing postgreSQL and rebooting Mint when recieved I would recieve the following error saying can't start postgres
while trying to run Django
could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain 
socket “/var/run/postgresql/.s.PGSQL.5432”?


sudo mkdir /var/log/postgresql
sudo chown postgres.postgres /var/log/postgresql
sudo su postgres
touch /var/log/postgresql/postgresql-9.1-main.log
/etc/init.d/postgresql stop
/etc/init.d/postgresql start

the above solution was from:

To fix postgress for once an all:

cd /usr/share/postgresql-common
sudo pico init.d-function

find start(){

and add the following:

if [ -d "/var/log/postgresql"]; then
  chmod 2775 /var/log/postgresql
else
  mkdir -m 2775 -p /var/log/postgresql
  touch /var/log/postgresql/postgresql-9.1-main.log
  chmod 2666 /var/log/postgresql/postgresql-9.1-main.log
fi
