Some suggestions, perhaps just based on my preference for verbosity:

<para>
Add cache of local locks (Jeff Janes)
</para>

<para>
This speeds lock release at statement completion in transactions
that hold many locks; it is particularly useful for pg_dump.
</para>

I think this is equally important for restoration of dumps, if the
restoration is run all in one transaction. (Making the dump and restoring
it have similar locking and unlocking patterns)

<para>
Split pgstat file in per-database and global files (Tomas Vondra)
</para>

<para>
This reduces the statistics management read and write overhead.
</para>

Should be "split pgstat file into", not "split pgstat file in"

Also, should it mention that the overhead reduction is particular to when a
cluster has a large number of databases?

Cheers,

Jeff
