I think I understand your point, however it would be very laborious after
you do all development to find out you need to de-normalize.

On your experience at which point it would actually help to do this
de-normalization in PostgreSQL? I know there are numerous factors ,but any
feedback based on previous experiences would help.

Right now the work I am doing is only for company internal use. If I was
to ever do work that outside users would have access to then I would be
looking at 100+ concurrent users.
