Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = git@github.com:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

To backup:
docker exec -u <your_postgres_user> <postgres_container_name> pg_dump -Fc <database_name_here> > db.dump

To drop db (Don't do it on production, for test purpose only!!!):
docker exec -u <your_postgres_user> <postgres_container_name> psql -c 'DROP DATABASE <your_db_name>'

To restore:
docker exec -i -u <your_postgres_user> <postgres_container_name> pg_restore -C -d postgres < db.dump
