to_char() gives the same answer with Oracle, as it is supposed to
and as you intended it to.
I personally don't find it all that disconcerting that the two give
different answers. Change the old, PG way and lots of old code
is likely to break. Change to_char() and the desired compatibility
with Oracle breaks.
I think it boils down to needing good documentation ???
