"* Adjust costing to force parallelism with partition aggregates."

If that's about 01474f5698, then it does not need to be mentioned.
All that commit does is update the regression tests so that they're
properly exercising what they were originally meant to test.

'Fixes and changes in PostgreSQL 15 Beta 3 include:'  should be
'Fixes and changes in PostgreSQL 15 Beta 4 include:'

I would say "Avoid crash in MERGE when called inside COPY or a CTE by
throwing an error early", so that it doesn't look like we're removing a
feature.

Thank you for putting this together!

Yeah, we don't want to create the wrong impression. I updated it per 
your suggestion (with minor tweaks) and removed the line that David 
mentioned around the test fix.

Thanks!
