You may as well double quote all column names in SQL queries.

Hi Philip,
You've probably realized by now that R doesn't like column names that
start with a number. If you try to access an R-dataframe column named
2B or 3B with the familiar "$" notation, you'll get an error:

The double quotes are required by SQL if a name is not of the form
letter-followed-by-any-number-of-letters-or-numbers or if the name is a SQL
keyword like 'where' or 'select'. If you are doing this from a function,
you may as well quote all the names.
