> The function signature in Scalar Function section is a little confusing. Because it's hard to distinguish keyword and parameters. Such as : {{EXTRACT(TIMEINTERVALUNIT FROM TEMPORAL)}}, user may not know TEMPORAL is a parameter after first glance. I propose to use {{<>}} around parameters, i.e. {{EXTRACT(<TIMEINTERVALUNIT> FROM <TEMPORAL>)}}
