Sure, but in the meantime, consider:
test=# select '12'::money * '2'::numeric;
?column?
----------
$24.00
(1 row)
test=# select '24'::money / '2'::numeric;
?column?
----------
$12.00
(1 row)
test=# select '24'::money / '12'::money;
ERROR: operator does not exist: money / money
LINE 1: select '24'::money / '12'::money;
^
HINT: No operator matches the given name and argument type(s). You
might need to add explicit type casts.
So we support:
a * b = c
c / b = a
but don't even *think* about c / a = b ???
The OP just wanted to add some symmetry to this, so that the
existing class could handle a not-uncommon use case more easily. As
far as I can see, the implementation of this operator could convert
two int64 values to numeric values and perform numeric division to
get the result. (I was going to mark the TODO as an easy one.) I
don't see how this change would affect what you want to do, one way
or the other.
