That is the heart of the matter, you should do what makes sense to you. 
If you can get the information you need in the manner you want then 
don't change things. Given the size of your datasets I don't see that 
changes will materially affect the performance of your queries. I am 
pretty sure most of the time the Postgres planner is resorting to a 
sequence scan anyway.
