Because the SQL standard says so.  If a cursor isn't declared WITH HOLD,
then it's implicitly closed at transaction commit, cf SQL:2011 4.33
"Cursors": 

    An open cursor that was not defined as a holdable cursor is also
    closed by a <commit statement>.

Also, 14.2 <cursor properties> says that WITHOUT HOLD is the default
assumption if you don't explicitly say WITH HOLD.

(Yes, we do support WITH HOLD.)
