   Compatibility
 
   
-   The draft SQL:2008 standard includes a TRUNCATE command,
-   but at this writing it is uncertain whether that will reach standardization
-   or be fully compatible with PostgreSQL's
-   implementation.
+   The SQL:2008 standard includes a TRUNCATE command with the syntax
+   TRUNCATE TABLE tablename.
+   The clauses CONTINUE IDENTITY/RESTART IDENTITY
+   also appear in that standard but have slightly different but related meanings.
+   Some of the concurrency behavior of this command is left implementation-defined
+   by the standard, so the above notes should be considered and compared with
+   other implementations if necessary.
