Specifies the cursor handle for the user component.
Syntax:
type HDBICur: Longint;
property Handle: HDBICur;
Description:
Use Handle only to bypass TPSQLUser methods and organize
your own processing of the raw data received from PostgreSQL server.
Many low level function calls require a cursor handle parameter. Handle is set to an
initial value when a component is opened. So, if it is used with a call that changes the current record
position, call Resync immediately after returning
from the PostgreSQL call.
