> This should be simple to add, since decimals can already be parsed from
> strings. Decimals will be represented in JSON as strings. If a decimal with
> different precision or scale is parsed from the string, should there be any
> acceptable conversions? (for example, if the column is of type {{decimal(5,
> 2)}} should {{"12.3"}} be an error or equivalent to {{"012.30"}}?)
