> 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.
</P
><P
> Every non-holdable open cursor is implicitly closed when a
transaction is terminated by <TT
CLASS="COMMAND"
>COMMIT</TT
> or
<TT
CLASS="COMMAND"
>ROLLBACK</TT
>. A holdable cursor is implicitly
closed if the transaction that created it aborts via
<TT
CLASS="COMMAND"
>ROLLBACK</TT
>. If the creating transaction
successfully commits, the holdable cursor remains open until an
explicit <TT
CLASS="COMMAND"
>CLOSE</TT
> is executed, or the client
disconnects.
