Want to dump every SQL query Magento runs?

In: lib/Zend/DB/Adapter/Adapter.php

public function query($sql, $bind = array())
{
    // connect to the database if needed
    $this->_connect();

    // is the $sql a Zend_Db_Select object?
    if ($sql instanceof Zend_Db_Select) {
        if (empty($bind)) {
            $bind = $sql->getBind();
        }

        $sql = $sql->assemble();
    }

    $time_start = microtime(true);

    // make sure $bind to an array;
    // don't use (array) typecasting because
    // because $bind may be a Zend_Db_Expr object
    if (!is_array($bind)) {
        $bind = array($bind);
    }

    // prepare and execute the statement with profiling
    $stmt = $this->prepare($sql);
    $stmt->execute($bind);

    // return the results embedded in the prepared statement object
    $stmt->setFetchMode($this->_fetchMode);

    $time_end = microtime(true);
    $time = $time_end - $time_start;

    echo "SQL[$time | $sql ]" . "\n<br />\n";
    return $stmt;
}
