Postgres working example link is pointing to the v3x Mongo working example link, and vice versa.

[zacharyad]

I am hoping to correct a linking mix up to help others in the future. There was a previous issue for the tutorial links being mixed up (issue #874). I believe this is part of that issue but was not cleaned up properly to include both the tutorial link AND the working example link.

Expected behavior

I expect to click on the link for the postgres working example github repo link and be directed to the postgres working example. github repo

Actual behavior

I click on the link for the postgres working example github repo link and I am directed to the mongo v3x working example. github repo

Steps to reproduce

• Click the links for postgres working example and the link for mongo working example.

Environment

• github.com (markdown links)
