Incubator-superset: Problem uploading CSV to PostgreSQL database

[Sascha-Gschwind]

When you try to upload a CSV that has parentheses in the title column to a PostgreSQL database it fails with an error, showing the column title.

If you upload the same file to a SQLite database it succeeds.

Expected results

The CSV can be successfully uploaded to a PostgreSQL database.

Actual results

The CSV can not be successfully uploaded to a PostgreSQL database.
