I already have the postgresql of latest version(14.0-1.pgdg21.04+1).
I want to setup dev environment for psycopg2() library locally and it requires libpq-dev for that.
Running sudo apt-get install libpq-dev gives following error
The following packages have unmet dependencies: libpq-dev : Depends: libpq5 (= 13.4-1) but 14.0-1.pgdg21.04+1 is to be installed E: Unable to correct problems, you have held broken packages.
It's because ubuntu repository() doesn't have the latest version yet.
But I've found that debian sid repository have the latest versionlibpq-dev (14.0-1)
I can download the .deb file and dpkg install it but the downside is I can't upgrade it. Also, I don't want to add debian in my sources list, because it might mess a lot of other things.
So, what's the easiest way to download this package?

Just install the required version of libpq5 and reinstall libpq-dev:
sudo apt-get install libpq5=13.4-1
sudo apt-get install libpq-devI suppose for psycopg2 you also need:
sudo apt-get install python3-dev
