ama very primitive user of Postgres and think of it as Microsoft Access on Steroids. I access it via Aqua Data, Studio,
butI don't think that makes any difference
 

Access is an application design tool with a built-in engine that's good for 
storing "small" amounts of data.

Postgresql is a database management system suitable for storing and 
replicating billions and billions and billions of large amounts of data, and 
analyzing it in a myriad of ways.  It requires "administration from the 
command line", as you're discovering.
