Heroku PostgreSQL connection problem

Hi Guys, I’m struggling in Heroku PostgreSQL connection… I don’t know what I’m doing wrong and I’m stuck in it for more than 3 days.

I’m not a software developer, and it’s my 4th deployment in all my life, so can someone give me some direction on how can I solve this problem?

I’m almost giving up =/

I just posted a Stackoverflow detailed question:

I would be eternally grateful to people that can give me some tips on how can I fix it and deploy my application.

Thank you very much in advance.
