Hmm? He's proposing storing the info in a system catalog. That hardly
seems "volatile"; it'll certainly survive a server restart.

Again, it's not clear what you've got in mind.
I agree with the point that this isn't completely transparent to
applications, but if an app is already using named prepared statements
it would surely be a pretty small matter to make it use this feature.
The app code would likely get simpler instead of more complex, since
you'd stop worrying about whether a given statement had been prepared
yet in the current session.
