We already did this, for a brief period of time, in #846, and then reverted back in #859, because of #849.

As detailed in #849, there's a subset of users that can't run with psycopg2-binary installation. So we're currently not forcing it. This means that until 2.8 (first source-only version) is released, psycopg2 will spit out a warning. It's annoying, but at least it's not breaking things. Once 2.8 is released, the warning should go away. As far as I understand, users that wish to use psycopg2-binary will still be able to install that over psycopg2. If my understanding is not correct, we'll have to figure out a way for users to select binary vs source installation after 2.8 is out.

Thank you for the PR!
