This is a post on how to install Postgres on Ubuntu 20.04, on Windows Subsystem for Linux (WSL). This should hopefully be a straightforward installation for you, which is done by following these 2 steps:
First, we need to update our local packages, by running the following apt command:
# update local packages sudo apt update
The next command will install Postgres. We’re including the ‘-contrib‘ package which will give us extra functionalities. After installing with the first command I need to restart the Postgres Service to resolve an “error: could not connect to server: No such file or directory” error message.
# install postgres on ubuntu sudo apt install postgresql postgresql-contrib # restart postgres service ubuntu sudo service postgresql restart
Once the installation completes, we can enter psql using the ‘postgres’ user that was automatically created during the installation.
# login to psql with the out of box postgres user sudo -u postgres psql \q (to quit back to terminal)
