This reverts commit 0b6a6aef.

regex pattern does not support sql casting using :: operator for example select mydate::date from mytable;

Removed is_int check and converted both comparisons into equality comparisons when expanding list parameters.

[DBAL-78] Add support for native sql list support in positional queries through the introduction of two new constants:

* Doctrine\DBAL\Connection::PARAM_STR_ARRAY
* Doctrine\DBAL\Connection::PARAM_INT_ARRAY

Replacement of arrays only works in conjunction with the Doctrine\DBAL\Connection::executeQuery() and executeUpdate() methods.
You need to pass the param constants into the third parameter called $types.
