I've no opinion on the not respecting aliases aspect of this, but both
the hstore and json emtpy keys case breaks the format: it's duplicate keys
that collapse to a single value, and expected keynames are missing.
The insidious bit about this bug though is that it works fine during testing
with the developers typically small data sets. It's only triggered in my case
when we the plan switches to index-only. Even an index scan works fine. I can't
imagine that there is code out there that _depends_ on this behavior. Just as
likely to me are that there exist systems that just have "can't reproduce" bugs
that would be fixed by this.
No, I can't imagine it either - it's utterly broken. That's the piece
that Tom is proposing to fix on the back branches. AIUI.
