The message returned when the cursor is successfully closed.
NOTICE: PerformPortalClose: portal "cursor" not found
The notice returned if the specified cursor
is either not declared, or not open.
Description
The CLOSE command closes an open cursor and frees the resources it was
using. Cursors should always be closed after they are no longer needed. Once a cursor is
closed, further operations are not allowed on it.
Note
Executing a COMMIT or ROLLBACK terminates the
current transaction, closing all open cursors.
Examples
The following example opens a transaction, declares the cur_publishers
cursor, and closes it:
booktown=# BEGIN;
BEGIN
booktown=# DECLARE cur_publishers CURSOR FOR SELECT * FROM publishers;
SELECT
booktown=# CLOSE cur_publishers;
CLOSE
