The application already quotes all column names :-) It's using a generic
framework which does not (and must not) rely on column names being
non-keywords.

This is correct -- in theory. In practice there are many average system
administrators which need an easy upgrade path. You may call this
unprofessional, but this is reality.

To put it on the point: Is postgres meant for average administrators or
