TBH, if I had 20-20 foresight, we'd not be having this discussion:
either I could see that you're right and this patch isn't going to
cause us enormous pain, or I could put my finger on exactly where
and why it's going to hurt us. But I can't do the latter today.
Nonetheless, this patch terrifies me. It's ugly, it's a serious
layering violation, and it flies in the face of very-long-standing
assumptions about the semantics of heap storage. My gut tells me
that we *will* regret shipping things this way. Nor am I impressed
with the amount of functionality we're gaining by taking such a risk.
regards, tom lane
