Peter Eisentraut bc3ae886a7 Forbid FOR PORTION OF with WHERE CURRENT OF
It is not clear how the implicit condition of FOR PORTION OF should
interact with the use of a cursor.  Normally, we forbid combining
WHERE CURRENT OF with other WHERE conditions.  The SQL standard only
includes FOR PORTION OF with <update statement: searched> and <delete
statement: searched>, not <update statement: positioned> or <delete
statement: positioned>, so it is easy for us to exclude the
functionality, at least for now.
