Yes, it is really a kluge that should be discussed. The main problem is that we don’t pass projection information to analyze scan (analyze begin scan relise only on relation information during initialization). And as a result we can’t benefit from column AMs during «analyze t(col)» and consume data only from target columns. This parameters were added to solve this problem.
