Glad to hear that, @marcos-costa.

Worked perfectly for me thank you so much @jadecorrea just a small doubt where do we enter for username and password

Had to do a bit of modification to the commands to work in elementary OS 6.1 Jólnir.

1. Replaced precise to focal (Ubuntu 20.04 LTS):

sudo sh -c "echo 'deb http://apt.postgresql.org/pub/repos/apt/ focal-pgdg main' > /etc/apt/sources.list.d/pgdg.list"

2. Replaced postgresql-9.3 to postgresql-9.6 (version latest i see at the time of writing)

sudo apt-get install postgresql-9.6 libpq-dev

Every other command is the same.

thanks...
