As to the argument about displaying a check or an X, why should that

max_of_blah ). I'm sure there's other examples people could think of.

Well, why not?  The question there is only how many marginal features
you want to stuff into psql, not whether it's the right place to stuff them.

I was more thinking it would be nice to be able to temporarily over-ride/wrap what an output function is doing. AFAIK that would allow this to work everywhere (row(), copy, etc). I don't know of any remotely practical way to do that, though.
