Overview
CLOSE frees the resources associated with an open cursor. After the cursor is closed, no subsequent operations are allowed on it. A cursor should be closed when it is no longer needed.
An implicit close is executed for every open cursor when a transaction is terminated by COMMIT or ROLLBACK.
Notes
PostgreSQL does not have an explicit OPEN cursor statement; a cursor is considered open when it is declared. Use the DECLARE statement to declare a cursor.
Usage
Close the cursor liahona:
CLOSE liahona;

CLOSE is fully compatible with SQL92.
