FROM STDIN</code> statements.</p>
<p>COPY FROM STDIN is parsed here instead of through sqlparser because the
<code>WITH (...)</code> option list is open: formats may accept options beyond
sqlparser’s COPY grammar (for example a line-protocol format taking
<code>precision</code>), and unknown options must reach the format codec rather
than fail statement parsing.</p>
<p>The parser commits to error reporting only after <code>FROM STDIN</code> has been
seen; anything else (like <code>COPY ... TO STDOUT</code>) is reported as
<a href="enum.CopyInScan.html#variant.NotCopyIn" title="variant servers::postgres::copy_in::parse::CopyInScan::NotCopyIn"><code>CopyInScan::NotCopyIn</code></a> so the caller falls back to the regular SQL
path.</p>
