This guide will walk you through the steps required to Install PostgreSQL 11 on Debian 10 (Buster). PostgreSQL is a powerful, highly-extensible database server written in C. It is the World’s most advanced relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
The first release of PostgreSQL 11 was on 2018-10-18 and you can check more details on the release page. Follow the few steps below to install PostgreSQL 11 on Debian 10 (Buster).
Step 1: Add PostgreSQL Repository
Start by ensuring everything is updated on your Debian 10 system.
sudo apt update
sudo apt -y upgrade
Then Import the repository signing key:
sudo apt install -y vim wget
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
Add the repository:
RELEASE=$(lsb_release -cs)
echo "deb http://apt.postgresql.org/pub/repos/apt/ ${RELEASE}"-pgdg main | sudo tee /etc/apt/sources.list.d/pgdg.list
Step 2: Install PostgreSQL 11 on Debian 10 (Buster)
Now install PostgreSQL 11 on Debian 10 Buster by running the command below.
sudo apt update
sudo apt -y install postgresql-11
The service is usually started after installation.
$ systemctl status postgresql
● postgresql.service - PostgreSQL RDBMS
Loaded: loaded (/lib/systemd/system/postgresql.service; enabled; vendor preset: enabled)
Active: active (exited) since Fri 2019-03-29 13:15:54 UTC; 3min 37s ago
Main PID: 1360 (code=exited, status=0/SUCCESS)
Tasks: 0 (limit: 1148)
Memory: 0B
CGroup: /system.slice/postgresql.service
We need to set PostgreSQL admin user Password:
$ sudo su - postgres
postgres@deb10:~$ psql -c "alter user postgres with password 'StrongDBPassword'"
ALTER ROLE
Step 3: Enable remote access (Optional)
By default, access to PostgreSQL database server is only from localhost.
$ ss -tunelp | grep 5432
tcp LISTEN 0 128 127.0.0.1:5432 0.0.0.0:* users:(("postgres",pid=15785,fd=3)) uid:111 ino:42331 sk:6 <->
Edit PostgreSQL 11 configuration file if you want to change listening address:
sudo vim /etc/postgresql/11/main/postgresql.conf
Add below line under CONNECTIONS AND AUTHENTICATION section.
listen_addresses = '*' # Don't do this if your server is on public network
You can also specify server IP Address
listen_addresses = '10.10.0.2' # Recommended for LAN connections to DB Server
Restart postgresql after making a change
sudo systemctl restart postgresql
Confirm
$ ss -tunelp | grep 5432
tcp LISTEN 0 128 0.0.0.0:5432 0.0.0.0:* uid:108 ino:74999 sk:a <->
tcp LISTEN 0 128 [::]:5432 [::]:* uid:108 ino:75000 sk:b v6only:1 <->
If you have an active UFW firewall, allow port 5432 for network connections.
sudo ufw allow 5432/tcp
Step 4: Test PostgreSQL Installation
Add a test database user:
$ sudo su - postgres
postgres@deb10:~$ createuser test_user1
Add the test database and grant ownership to test_user1:
postgres@deb10:~$ createdb test_db -O test_user1
Set user password:
postgres@deb10:~$ psql
psql (11.2 (Debian 11.2-2))
Type "help" for help.
postgres=# alter user test_user1 with password 'DBUserPassword';
ALTER ROLE
Login to test_db database:
postgres@deb10:~$ psql -l | grep test_db
test_db | test_user1 | UTF8 | en_US.UTF-8 | en_US.UTF-8 |
postgres@deb10:~$ psql test_db
psql (11.2 (Debian 11.2-2))
Type "help" for help.
test_db=#
Create a table and add some dummy data:
test_db=# create table test_table ( id int,first_name text, last_name text );
CREATE TABLE
test_db=# insert into test_table (id,first_name,last_name) values (1,'John','Doe');
INSERT 0 1
Show table data:
test_db=# select * from test_table;
id | first_name | last_name
----+------------+-----------
1 | John | Doe
(1 row)
test_db=#
Let’s drop our test database to retain clean installation.
postgres@deb10:~$ dropdb test_db
That’s all. You have successfully installed PostgreSQL 11 on Debian 10 (Buster).
