Let's do both. Some already map to existing functions, which mean you
get to do this in your driver I suppose. Others, like many of the math
routines, should/could be in the backend.

How do you want to organize attacking these? I can help now with
suggesting mappings for existing functions (e.g. date_part('dow',
datetime) gives you "dayofweek") and can help with new functions in a
month or two. Or, perhaps others can help with that more quickly...
