On that note, since it seems that the large objects that I've
just started using aren't likely to go away right this moment (and
their interface works for what I'm doing anyway), what is a good way
to write backend functions in C that will deal with large objects?

I would like to write some backend routines that will do
things like resize, watermark, and cache graphics files. If I
pass an Oid into a function, how would I access its data?
