Install postgresql on Debian Squeeze / How to install PostGreSQL on Obsolete Debian installation


If you're in position like me to be running an old version of Debian (Squeeze) and you need to install PostgreSQL you will notice that the Debian 6.0 standard repositories are no longer active and apt-get update && apt-get upgrade are returning errors, thus because this Debian release is already too old and even the LTS repositories are inactive it is impossible to install postgresql with the usual.

To get around the situation first thing I did was to try to add followin Debian  repositories. to /etc/apt/sources.list

deb squeeze-backports-sloppy main
deb squeeze main contrib non-free
deb squeeze-lts main contrib non-free

After adding it I continued getting missing package errors while trying:

# apt-get update && apt-get install postgresql postgresql-client


E: Some index files failed to download. They have been ignored, or old ones used instead.

Thus I googled a bit and I found the following PostgreSQL instructions working Debian 7.0 Wheeze and decided to try it 1 in 1 just changing the repository package wheezy word with squeeze
in original tutorial postgre's deb repositories are:


deb wheezy-pgdg main

I've only changed that one with:


deb squeeze-pgdg main


I guess though this worked for Debian Squeeze installing current versions such as Debian 8.0 Jessis and newer wouldn't be a prolem if you just change the debian version keyword witht he distribution for which you need the postgresql package

Here is all the consequential steps I took to make the PostgreSQL 9.5 running on my old and unsupported Debian 6.0 Squeeze

Create /etc/apt/sources.list.d/pgdg.list. The distributions are called codename-pgdg. In the example, replace wheezy with the actual distribution you are using:

# vim /etc/apt/sources.list.d/pgdg.list


deb squeeze-pgdg main

debian:~# apt-get –yes install wget ca-certificates debian:~# wget –quiet -O – | sudo apt-key add – debian:~# apt-get update debian:~# apt-get upgrade debian:~# apt-get –yes install postgresql-9.5 pgadmin3

Next step is to connect to PostGreSQL and create database user and a database # su – postgres $ psql

Create a new database user and a database:

postgres=# CREATE USER mypguser WITH PASSWORD 'mypguserpass'; postgres=# CREATE DATABASE mypgdatabase OWNER mypguser;



# createuser mypguser #from regular shell # createdb -O mypguser mypgdatabase

Quit from the database

postgres=# q

Connect as user mypguser to new database

# su – mypguser $ psql mypgdatabase


# psql -d mypgdatabase -U mypguser

If you get errors like:

psql: FATAL: Ident authentication failed for user "mypguser"

edit pg_hba.conf in /etc/postgresql/9.5.Y/main/pg_hba.conf


local all all trust # replace ident or peer with trust

reload postgresql

/etc/init.d/postgresql reload …


To make sure that PostGreSQL is running on the system check the following processes are present on the server:




root@pcfreak:/var/www/images# ps axu|grep -i post postgres 9893 0.0 0.0 318696 16172 ? S 15:20 0:00 /usr/lib/postgresql/9.5/bin/postgres -D /var/lib/postgresql/9.5/main -c config_file=/etc/postgresql/9.5/main/postgresql.conf postgres 9895 0.0 0.0 318696 1768 ? Ss 15:20 0:00 postgres: checkpointer process postgres 9896 0.0 0.0 318696 2700 ? Ss 15:20 0:00 postgres: writer process postgres 9897 0.0 0.0 318696 1708 ? Ss 15:20 0:00 postgres: wal writer process postgres 9898 0.0 0.0 319132 2564 ? Ss 15:20 0:00 postgres: autovacuum launcher process postgres 9899 0.0 0.0 173680 1652 ? Ss 15:20 0:00 postgres: stats collector process root 14117 0.0 0.0 112404 924 pts/1 S+ 16:09 0:00 grep -i post



Well that's all folks now you will have the postgresql running on its default port 5433:


debian:/etc/postgresql/9.5/main# grep -i port postgresql.conf
port = 5433 # (change requires restart)
# supported by the operating system:
# supported by the operating system:
# ERROR REPORTING AND LOGGING # %r = remote host and port



Well that's it folks thanks The Lord Jesus Christ grace by the prayers of John The Baptist and Saint Sergij Radonezhki it works 🙂
