+
+    <P>The PostgreSQL team tries very heard to maintain compatability across
+    minor releases. So upgrading from 7.2 to 7.2.1 does not require a dump a
+    restore. However, new features are continuously being adding and
+    sometimes this requires new fields to be added to system tables.
+
+    <P>These changes may be across many tables and so maintaining backward
+    compatability would be quite difficult. Thus, restoring from a dump is
+    required to make everything work.
+
+    <P>Note that the actual on-disk file format does not change very often,
+    a feature the pg_upgrade script uses quite successfully. There the dump
+    is used create the necessary information in the system tables. The data
+    files are then just copied across. This method is not as guarenteed as
+    the dump/restore method but when it works it can make upgrades very
+    efficient.
