Timescale at least has many users, I don't know about the others. But they won't be happy if we let things be. IMO we should rewrap ... especially 12, since there won't be a next one.
ISTM that we have spare bytes where we could place that boolean without breaking ABI. In x86_64 there's a couple of 4-byte holes, but those won't be there on x86, so not great candidates. Fortunately there are 3-byte and 7-byte holes also, which we can use safely. We can move the new boolean to those location. The holes are different in each branch unfortunately. -- Álvaro Herrera Breisgau, Deutschland — https://www.EnterpriseDB.com/ "Use it up, wear it out, make it do, or do without"
