Hi Below are a few commits which are not referenced in the current iteration of the release notes, but which seem worthy of inclusion. Apologies if they have been previously discussed, or I'm overlooking something obvious. d09dbeb9b Speedup hash index builds by skipping needless binary searches "Testing has shown that this can improve hash index build speeds by 5-15% with a unique set of integer values." e09d7a126 Improve speed of hash index build. "This seems to be good for overall speedup of 5%-9%, depending on the incoming data." 594f8d377 Allow batching of inserts during cross-partition updates. seems reasonable to mention this as it's related to 97da48246, which is mentioned in the notes 1349d2790 Improve performance of ORDER BY / DISTINCT aggregates This is the basis for da5800d5, which is mentioned in the notes, but AFAICS the latter is an implementation fix for the former (haven't looked into either in detail though). The following are probably not headline features, but are the kind of behavioural changes I'd expect to find in the release notes (when, at some point in the far and distant future, trying to work out when they were introduced when considering application compatibility etc.): 13a185f54 Allow publications with schema and table of the same schema. 2ceea5adb Accept "+infinity" in date and timestamp[tz] input. d540a02a7 Display the leader apply worker's PID for parallel apply workers.
