Can I a question I haven't been able to answer myself?

In your webapp using POSTGRESQL, are you actually using SQL statements in your code to retrieve the data? Or is there some other way to get at it?

I think the search term you are looking for is O.R.M. Object Relational Mapping.

Rather than me explaining it here, the rails guides[1] give you a good overview.
