Are you sure pg_dump is installed ?

hello, Estoy usando openshift 3, como hago para crear un backup de la base de datos en mi maquina local windows, y como lo restauro

[iAnanich]

pg_dump requirement should be listed on "Installation" section of ReadTheDocs

I also encountered this after attempting to run using django inside a dockerized container of alpine linux. 

As far as I can tell, Alpine's minimum  postgres dependency for psycopg2  is postgres-dev, however you must also apk install postgres-client to make pg_dump available on that machine.

Once you've done this, you're able to run ./manage.py dbbackup just fine.

A few more notes and links here. I agree with @iAnanich about considering adding a note about this in the docs.
