-      This fixes some cases where a base backup taken concurrently
-      with <command>CREATE DATABASE</command> could produce a corrupt
-      image of the new database.
+      If an operating system crash occurred during or shortly
+      after <command>CREATE DATABASE</command>, recovery could fail, or
+      subsequent connections to the new database could fail.  If a base
+      backup was taken in that window, similar problems could be observed
+      when trying to use the backup.  The symptom would be that the
+      database directory, <filename>PG_VERSION</filename> file, or
+      <filename>pg_filenode.map</filename> file was missing or empty.

-      Prevent examining system catalogs with the wrong snapshot during

-
-     <para>
-      If decoding begins partway through a transaction that modifies
-      system catalogs, the decoder may not recognize that, causing it to
-      fail to treat that transaction as in-progress for catalog lookups.
-      This fix deals with the case that a top-level transaction is already
-      marked as containing catalog changes, but its subtransaction(s) are
-      not.
