The commit_delay improvements should stay under performance, where I
previously indicated they should be - it's clearly a notable new
feature (commit_delay is way more effective now), as opposed to a
tweak to the semantics of an existing feature. The fact that the
behavior was changed could be separately noted, alongside the fact
that Simon made commit_delay PGC_POSTMASTER (this is already
separately noted anyway).

Similarly, I think that this is a new feature that needs a separate
compatibility note:

Allow in-memory sorts to use their full memory allocation (Jeff Janes)

It's possible that people were previously over-allocating memory to
compensate for the server's former unwillingness to make full use of
work_mem. You should specifically warn against that.

OK, I moved commit_delay back to performance, and moved in-memory sorts
up to compatibility.
