Ahh, Now I see why you were worried about people calling you a witch :)

On another note, I do wonder if we could avoid more confusion by just
reordering the arguments. In-fact I bet the original argument
ordering was done precisely so it would match the 1 argument version.

I dunno about anyone else but (a, ',' order by a) just looks weird.

Or in other words, any thoughts on:
select string_agg(delim, expression);

I don't want to stretch this out, but while we are making changes...
