Because this(cash.c):

https://git.postgresql.org/gitweb/?p=postgresql.git;a=blob;f=src/backend/utils/adt/cash.c;h=d093ce80386f4cf61f3127f3cfe77181f4edfed5;hb=HEAD

has this?:

/* cash_in()
   91  * Convert a string to a cash data type.
   92  * Format is [$]###[,]###[.##]
   93  * Examples: 123.45 $123.45 $123,456.78
   94  *
   95  */

The 1000s(group) separator is determined by LC_NUMERIC and I don't 
believe that is used by the money type.
