Hi All,


I have a procedure which contains only one Select statement. The
procedure take more time than expected to complete, the select statement
inside the procedure was taking about 2 minutes to complete. 


After running a Vacuum Analyze on the underlying tables the select
statement could complete within seconds. But the procedure was still
taking long time. 


I tried after recreating the procedure, the procedure is taking only a
few seconds after recreation.


Why the procedure is not getting the performance advantage of Vacuum
