I've never seen a need for zero-padding XIDs or PIDs, frankly. Can you imagine the mess if we ever grew XIDs to 64 bits? And what about OS-level configurability of PIDs? I don't know that there's a good way to learn their widths. I don't think it's worth of a comment even. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
