Is there any consensus about whether to include these two parameters as GUCs or constants if my patch is to be accepted?
(1) sync_scan_threshold: Use synchronized scanning for tables greater than this many pages; smaller tables will not be affected. (2) sync_scan_offset: Start a new scan this many pages before a currently running scan to take advantage of the pages that are likely already in cache. Right now they are just constants defined in a header, but a GUC might make sense. I'd like to know which version is more acceptable when I submit my final patch.
