Sure. I'm not the man for writing very clear English sentences.
I may be more fluent in C;-)

I don't know about postgreSQL responsability, but I am a teacher using
postgreSQL as a tool for teaching database. I don't need hints, but my
students may find sql a little bit easier to grasp if they have a little
bit more help from the error reports.
I can understand that this is not the main agenda of postgresql, which
is more about new features, better performance and sustained stability.
But it is my agenda as a teacher.
