<para>

a utility that creates logical replicas from physical standbys
</para>

This description is okay but according to me, the more compelling use
case is that this new utility helps to allow online upgrades of
physical replication setup as explained in the blog [1]. See the
section: "Upgrading Streaming (Physical) Replication Setup".

</listitem>
<listitem>
<para>
<link
linkend="pgupgrade"><application>pg_upgrade</application></link> now
preserves replication slots on both publishers and subscribers
</para>

It is better to write the above statement as:
"pg_upgrade</application></link> now preserves replication slots on
publishers and full subscription's state on subscribers". This is
because replication slots are preserved on publishers. The subscribers
preserve the subscription state.
