Steps on Ubuntu 18.04 64 bit:

- Clone psycopg2 from *https://github.com/psycopg/psycopg2.git
<https://github.com/psycopg/psycopg2.git>*
- Activate the virtual environment.
- Add path of PostgreSQL 10(/opt/PostgreSQL/10/bin) to PATH variable, so
that psycopg2 will compile against libpq version greater or equal to
100000.
- Go to the psycopg2 folder and run the following:
- python setup.py build
- python setup.py install
- It will create psycopg2-2.8.dev0-py2.7-linux-x86_64.egg
- Remove/Move all other folders or files with the name of "psycopg2"
from site-packages.
