The configuration parameter <varname>checkpoint_segments</varname> has
158+
been removed. Its place is taken by the new
159+
setting <xref linkend="guc-max-wal-size">. If you had previously
160+
tuned <varname>checkpoint_segments</varname>, the following formula will
161+
give you an approximately equivalent setting:
162+
<programlisting>
163+
max_wal_size = (3 * checkpoint_segments) * 16MB
164+
</programlisting>
165+
Note that the default setting for <varname>max_wal_size</varname> is
166+
much higher than the default <varname>checkpoint_segments</varname> used
167+
to be, so setting this might no longer be necessary.
