Have you gone through the tutorial? If not, I suggest doing that. From there, once you have a solid base knowledge, you will be able to more easily understand the documentation and use other sources for more technical problems. As far as whether you should outsource it - how much database work does involve? It really depends on what your goals are, and whether you have time, or money. I suggest asking your technical question on stackoverflow.com if you haven't already, it's a much more fitting place to get help on that sort of thing.

Which tutorial? I saw few tutorials on youtube and one on Udemy (I am in halfway). But most youtube tutorials are limited to how to create a table, add columns in pgadmin3. But the postgresql tutorial in Udemy is decent. Thank you for the feedback.
