I have the following problem, every time I turn on my machine, I go to the terminal and give sudo service postgresql status , it always appears 9.3/main (port 5432): down .

On other machines I have installed, it starts along with ubuntu, and when I run the same command appears 9.3/main (port 5432): online , I did nothing different, but it seems that my machine is missing some configuration.

Every time I use the database for the first time, I need to start the service.

At the time of installation, the following message was displayed, I do not know if it has something to do with the error: No PostgreSQL clusters exist; see "man pg_createcluster"

I'm using Ubuntu 14.04 and Postgresql 9.3

postgresql.conf file :

# - Connection Settings -

#listen_addresses = 'localhost'     # what IP address(es) to listen on;
                # comma-separated list of addresses;
                # defaults to 'localhost'; use '*' for all
                # (change requires restart)
port = 5432             # (change requires restart)
max_connections = 100           # (change requires restart)
# Note:  Increasing max_connections costs ~400 bytes of shared memory per
# connection slot, plus lock space (see max_locks_per_transaction).
#superuser_reserved_connections = 3 # (change requires restart)
unix_socket_directories = '/var/run/postgresql' # comma-separated list of directories
                # (change requires restart)
#unix_socket_group = ''         # (change requires restart)
#unix_socket_permissions = 0777     # begin with 0 to use octal notation
                # (change requires restart)
#bonjour = off              # advertise server via Bonjour
                # (change requires restart)
#bonjour_name = ''          # defaults to the computer name
                # (change requires restart)

When installing Postgres the following information is displayed:

Removing obsolete dictionary files:
 * No PostgreSQL clusters exist; see "man pg_createcluster"
Processing triggers for ureadahead (0.100.0-16) ...

Thank you.

If at any point in your installation you saw a message similar to:

warning: Please check that your locale settings:
 LANGUAGE = (unset),
 LC_ALL = (unset),
 LC_TIME = "de_DE.UTF-8",
 LC_MONETARY = "de_DE.UTF-8",
 LC_ADDRESS = "de_DE.UTF-8",
 LC_TELEPHONE = "de_DE.UTF-8",
 LC_NAME = "de_DE.UTF-8",
 LC_MEASUREMENT = "de_DE.UTF-8",
 LC_IDENTIFICATION = "de_DE.UTF-8",
 LC_NUMERIC = "de_DE.UTF-8",
 LC_PAPER = "de_DE.UTF-8",
 LANG = "en_US.UTF-8"
    are supported and installed on your system.

This means that PostgreSQL could not create the cluster because of the above error. To fix the problem:

1) Reconfigure your premises:

# dpkg-reconfigure locales

2) Create the cluster correctly (my version is 9.3):

# pg_createcluster 9.3 main --start

3) Start PostgreSQL:

# /etc/init.d/postgresql start

You probably have not put postgresql to boot into boot . On the terminal run the command:

sudo update-rc.d postgresql defaults

For more information, see update-rc.d(8) .

Following the accepted response and some information I saw in the stackexchange: link (if you still do not try to read this)

Make sure the socket can be created

We have to make sure the socket can be created, so make sure the / var / run / postgresql directory exists and you have the correct permissions (read and write)

Let's do a test with TCP / IP

change your postgresql.conf to run on IP 127.0.0.1 to see what happens, there may be a bug with sockets maybe or something, even though it's a kick you can try.

Getting Started Correctly

According to the original topic (bug?) To start the postgre you will need the -h key, which specifies a host. Like this:

psql -h 127.0.0.1

If it still does not work

If nothing works, you have 2 options, in order of recommendation, 1 best and 2 worst:

1- apt-get with some hacks ..

Since Ubuntu has its own package system, you can completely reinstall postgre through apt-get and some more hacks that I found in Russian (?) link

sudo apt-get purge postgresql postgresql-contrib   # Remover configurações e o pacote

rm -r /etc/postgresql/
rm -r /etc/postgresql-common/
rm -r /var/lib/postgresql/
userdel -r postgres
groupdel postgres

sudo apt-get install postgresql postgresql-contrib # Reinstalar tudo

Now that we've reinstalled, if you still get a clustered error message:

pg_lsclusters
pg_createcluster 9.3 main --start

If it still does not start, check your script in /etc/init.d/(postgresql?) and add this:

#-- EDITADO --#
#POSTGRE FIX#
# create socket directory
if [ -d /var/run/postgresql ]; then
  chmod 2775 /var/run/postgresql
else
  install -d -m 2775 -o postgres -g postgres /var/run/postgresql
  [ -x /sbin/restorecon ] && restorecon -R /var/run/postgresql || true
fi
#--/EDITADO--#

2- Formatting or giving up your life

This is the least advised, but if it worked on other machines, you could format it to see what happens ... Or do a lot of gambiarra with the risk of damaging the system.

Notes

You may want to read this documentation file to help set up: link

And this OS issue can also help: link

It was all I found, if nothing works, you better reinstall Ubuntu or create another partition for another installation, or run on the VM ...

Anything comments on the answer
