Comment(by pracine):

 I guess the person who answered your question in the mailing list was
 speaking about set of rows when you mean set of columns. It is true that
 aggregates can't return set of rows. I don't know if they can return a set
 of column. Maybe by defining the final function properly.

 My prototype of ST_SummaryStatAgg() in the Add-ons DO return a set of
 column by the mean of a type. But I guess we don't want to add new type
 like we used to.
