<title>Compatibility</title>
<para>
The draft SQL:2008 standard includes a <command>TRUNCATE</command> command,
but at this writing it is uncertain whether that will reach standardization
or be fully compatible with <productname>PostgreSQL</productname>'s
implementation.
The SQL:2008 standard includes a <command>TRUNCATE</command> command with the syntax
<literal>TRUNCATE TABLE <replaceable>tablename</replaceable></literal>.
The clauses <literal>CONTINUE IDENTITY</literal>/<literal>RESTART IDENTITY</literal>
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.
