When would the differences between these calenders actually show
up? I can only think of it affecting input/output routines and the
date_part,date_trunc,to_date and to_char routines. But am I missing
something?
If that's all, then how about just treating the current PG
date types as Julian days (as far as I know, that's how it's
treated internally anyway) and providing a multi-calender set of
date_part,date_trunc,to_date and to_char routines. I.e. leave out the
input/output routines.
Doing this would be much easier, but less fun, than creating whole new
types and having to modify the parser as well to recognize the new
syntax.
