I still assert that there will always only be one row to this query. This
is an aggregate query, so all the rows with ycis_id = 15, will be
aggregated. Since ycis_id is the identifying part of the query, it should
not need to be grouped.

My question, is it a syntactic technicality that PostgreSQL asks for a
"group by," or a bug in the parser?
