Data dump fails on tables with quoted identifiers

While dumping a table with a quoted identifier `numeric`, doctrine failed because the constructed query had an invalid alias the field: c__`numeric`.

Output:
SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '`numeric`, c.alpha3 AS c_alpha3, c.alpha2 AS calpha2 FROM country_codes c' at line 1. Failing Query: "SELECT c.country AS ccountry, c.`numeric` AS c`numeric`, c.alpha3 AS calpha3, c.alpha2 AS c_alpha2 FROM country_codes c"

I know that using quoted identifiers is discouraged but I think this could be easily solvable.

Thanks.
