+2020-07-20 [f5dff45962] Rename wal_keep_segments to wal_keep_size.

+ <para>
+ This determines how much WAL to retain for the standby server,
+ specified in megabytes rather than number of files. If you
+ previously used <varname>wal_keep_segments</varname>,
+ the following formula will give you an approximately equivalent setting:
+<programlisting>
+wal_keep_size = wal_keep_segments * wal_segment_size (typically 16MB)
+</programlisting>
