How to setup PostgreSQL and DBeaver on WSL.

Spent a few hours trying to configure PostgreSQL and DBeaver on wsl. Hope this helps.

Installing postgresql on wsl terminal

$ sudo apt update
$ sudo apt install postgresql postgresql-contrib
$ psql --version

• Give it a password that we will use in Dbeaver when testing connection.

$ sudo passwd postgres

• Restart Terminal.

• Check status and start PostgreSQL service.
  

$ sudo service postgresql status
$ sudo service postgresql start

• You should get a prompt asking for your password.

If you didn't, then type :

$ su - postgres
$ psql

• After entering your password you should see this

postgres=#

• Keep terminal open

DBeaver Setup

• Open DBeaver after installing from here

• Ctrl - Shift - N to make a new connection and select PostgreSQL.

• Fill your password you entered earlier and click test connection.

• It should ask you to download some drivers. After downloading it should be working.

If you get an error, lets try reseting password and creating dummydb.

• go back to your terminal \q out and

$ sudo -u postgres createuser <username>
$ sudo -u postgres createdb <dummydbname>
$ sudo -u postgres psql

psql=# alter user postgres with encrypted password '<password>'
psql=# grant all privileges on database <dbname> to postgres 

• Close DBeaver and retry testing your connection.

• If you get an connection error
  

sudo ufw allow 5432/tcp
# You should see "Rules updated" and/or "Rules updated (v6)"
sudo service postgresql restart

• Open powershell as admin wsl --shutdown

Start postgresql service and Retry connection.
