Let's quote what you wrote and see what it tells us:

"I like a few things with Mongodb. However, I found certain queries I was

 when I had to join several tables to calculate some logic."

"I found the ODM to be very limiting compared to what Active Record offered
 with traditional (SQL) database systems."

"I feel more comfortable working with PostgreSql than Mongodb. Only because
 I can join tables and do anything with the data."

Based on what you've said it looks to me like you should stick with PostgreSQL. Keep an eye on MongoDB and use it if and when it's appropriate. But given what you've said it sounds like PG is a better fit for you at present.
