What about this?  Is the tuple currently being evaluated (I suppose in
the case of a sequential scan) available in the context of a function call?

AFAIK that *very* specific case would work, because the executor would be handing you the raw tuple. Not a great bet to make though. Also, there should be a macro somewhere that will tell you whether you have a full tuple or not. You'd want to make sure to check that an throw an error if you weren't handed a full tuple.
