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. -- Sam http://samason.me.uk/ -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
