# If you want to insert numbers you must be explicit, unfortunately. Use the
# :validations option to pass a hash of property types. Currently the only one
# besides the default is :long (the default is to make the value a string and
# then creating a byte array from the string, this works with the :bytes,
# :ascii and :utf8 validations [read "column value types"] if the string has
# the right encoding).
