I can't completely agree with you. I use only PostgreSQL, but I used to
help my colleague working with Oracle (he was a novice), and I looked at
his result of EXPLAIN (it was different from what PostgreSQL gives, but
quite clear). I am not sure that in every database engine PRIMARY KEY
constraint is implemented using index. So you give some astonishment to
people not familiar with PostgreSQL but familiar with some other DBMS
and able to understand result of EXPLAIN.
