-    In addition to the local temporary table, SQL92 also defines a

-    Global temporary tables are also visible to other sessions.
+    Although the syntax of <literal>CREATE TEMPORARY TABLE</literal>
+    resembles that of SQL92, the effect is not the same.  In the standard,
+    temporary tables are associated with modules; a temporary table is created
+    just once and automatically exists (starting with empty contents) in every
+    session that uses the module.

-    <literal>ON COMMIT DELETE ROWS</>.  However, the behavior of
