Different query result under transaction

[Pader]

In transaction example use execute() to do a query and get result, not query():

mysql/examples/6-transaction.php

Lines 20 to 24 in f14d62f

 $result = yield $transaction->execute("SELECT * FROM tmp WHERE a >= ?", [5]); // Two rows should be returned. 
  
 while (yield $result->advance()) { 
     \var_dump($result->getCurrent()); 
 } 

When change to query() I get this error:

Error: Call to undefined method Amp\Mysql\Internal\ResultProxy::advance()

I found that execute() return Amp\Mysql\PooledResultSet, but query() return Amp\Mysql\Internal\ResultProxy.

But in non-transaction query, the query() and execute() always return 'Amp\Mysql\PooledResultSet`.

Is that a problem?
