OK, updated text:

	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 already
	md5-hashed.  Also, the legacy (and undocumented) boolean-like
	values which were previously synonyms of <literal>md5</literal>
	are no longer accepted.
