* Remove Money type, add money formatting for decimal type
* Change NUMERIC to enforce the maximum precision, and increase it
+* Add NUMERIC division operator that doesn't round?
+
+ Currently NUMERIC _rounds_ the result to the specified precision.
+ This means division can return a result that multiplied by the
+ divisor is greater than the dividend, e.g. this returns a value > 10:
+
+ SELECT (10::numeric(2,0) / 6::numeric(2,0))::numeric(2,0) * 6;
+
+ The positive modulus result returned by NUMERICs might be considered
+ inaccurate, in one sense.
+
* Add function to return compressed length of TOAST data values
* Allow INET subnet tests using non-constants to be indexed
* Add transaction_timestamp(), statement_timestamp(), clock_timestamp()
