+    <title>Overflow Text</title>
+ 
+    <para>
+     Occasionally text is too wide for the printed margins, and in
+     extreme cases, too wide for the printed page, e.g.  non-wrapped
+     text, wide tables.  Overly wide text generates <quote>Overfull
+     hbox</quote> messages in the TeX log output file, e.g.
+     <filename>postgres-US.log</> or <filename>postgres-A4.log</>.
+     There are 72 points in an inch so anything reported as over 72
+     points too wide will probably not fit on the printed page (assuming
+     one inch margins).  To find the <acronym>SGML</acronym> text
+     causing the overflow, find the first page number mentioned above
+     the overflow message, e.g.  <literal>[50 XXX]</> (page 50), and look
+     at that page in the <acronym>PDF</acronym> file to see the overflow
+     text and adjust the <acronym>SGML</acronym> accordingly.
