[R-sig-DB] DBI column names

Yes.  One idea for the name for the argument might be
check.names= . This is the same argument name used
in read.table.  The value could be TRUE, FALSE or a custom
function.  TRUE would use make.db.names and FALSE would
use the identity function.  The default would be TRUE for
compatibility with the existing function.

Another possibility is associating the value with the driver
or the connection; however, that may seem inconsistent to
users if dbWriteTable uses it and other functions do not.
