OK, what I was trying to say was that if you dump/restore, and the old
password was md5, the newly-restored password will be md5, but it was
very unclear. I changed it to this:
<listitem>

-->
<para>
Change the default of the password_encryption server parameter to
scram-sha-256 (Peter Eisentraut)
</para>
<para>
Previously it was md5. All new passwords will be stored as SHA256
unless this server variable is changed or the password is specified
in md5 format. Also, the legacy (and undocumented) boolean-like
values which were previously synonyms for <literal>md5</literal>
are no longer accepted.
</para>
