Right, so if this is done by trying to extend Daniel Verite's icu_ext
extension (link given earlier) and Robert's idea of a fast-castable
type, I suppose you might want now()::icu_date + '1 month'::internal
to advance you by one Ethiopic month if you have done SET
icu_ext.ICU_LC_TIME = 'am_ET@calendar=traditional'.  Or if using my
first idea of just sticking with the core types, perhaps you'd have to
replace stuff via search path... I admit that sounds rather error
prone and fragile (I was thinking mainly of different functions, not
operators).  Either way, I suppose there'd also be more explicit
functions for various operations including ones that take an extra
argument if you want to use an explicit locale instead of relying on
the ICU_LC_TIME setting.  I dunno.
