IIRC, the main pain point is providing an option for CREATE DATABASE
to set the value.  If you chase down all the references to lc_collate
you'll get the picture.

It'd probably be worth doing if money were less deprecated, but right
now I can't get excited about it.

Actually ... the thing that might turn money into a less deprecated type
is if you could set lc_monetary per column.  I wonder whether Peter's
collation hack could be extended to deal with that.
