​Except I have to define the table with money so that json_populate_record
uses the correct cast. But yes, when actually using the data, or if I
decide to make a view on top of the table, I can cast from money to numeric.

I guess I could define a custom type using money and then define the table
using numeric and transform in between; but its yet another definition to
keep in sync.

Money perfectly meets my current need and no longer has my scorn.
