Well, to be honest it should probably error if more
than one row is returned since it seems to be like
a scalar subquery in usage, but I don't think that's
what you want either. The question is what value
from the select list is put into var when multiple
rows are returned?

I don't have 7.1.2, but 7.1.3 seems to act like 7.2 in
this.
