DBAL-1214: MySQL has gone away using ImportCommand

[doctrinebot]

Jira issue originally created by user sylvain:

Importing a fairly large SQL file (a MySQL dump) fails with a MySQL has gone away error.

When reading the ImportCommand code, I see that this issue is already "fixed" by checking if the connection is an instance of \Doctrine\DBAL\Driver\PDOConnection.

The problem is that I don't see how the connection could be an instance of this class since it doesn't extend \Doctrine\DBAL\Connection.

If I'm wrong, then I don't know how to configure my connection to extend the PDOConnection class. Thanks for your help on that :D

Irrelevant as of #3241.
