Yeah, I don't quite understand this problem, and I tend to agree that it likely isn't this patch's fault. However, for the moment I'm going to avoid pushing the patch you propose because maybe there's a bug elsewhere and it'd be good to understand it. I'm looking at it now.
If others would prefer me to push David's patch (or do so themselves), I'm not dead set against that. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
