-    In the current release (v7.0), <productname>Postgres</productname>
-    evaluates all default expressions at the time the table is defined.
-    Hence, functions which are "non-cacheable" such as
-    <function>CURRENT_TIMESTAMP</function> may not produce the desired
-    effect. For the particular case of date/time types, one can work
-    around this behavior by using 
-    <quote>DEFAULT TEXT 'now'</quote>
-    instead of
-    <quote>DEFAULT 'now'</quote>
-    or
-    <quote>DEFAULT CURRENT_TIMESTAMP</quote>.
-    This forces <productname>Postgres</productname> to consider the constant a string
-    type and then to convert the value to <type>timestamp</type> at runtime.
