-   This command is modeled after an Oracle
-   feature.  There is no command with equivalent functionality in
-   the SQL standard.  However, a combination of CREATE
-   TABLE and INSERT ... SELECT can
-   accomplish the same thing with little more effort.
+   CREATE TABLE AS is specified by the SQL2003
+   standard. There are some small differences between the definition
+   of the command in SQL2003 and its implementation in
+   PostgreSQL:
+
+   
+    
+     
+      The standard requires parentheses around the subquery clause; in
+      PostgreSQL, these parentheses are
+      optional.
+     
+    
+
+    
+     
+      The standard defines an ON COMMIT clause;
+      this is not currently implemented by PostgreSQL.
+     
+    
+
+    
+     
+      The standard defines a WITH DATA clause;
+      this is not currently implemented by PostgreSQL.
