Why the procedure is not getting the performance advantage of Vacuum

Plan caching by the function, probably. Try disconnecting the session
and reconnecting to prove the hypothesis.

If it is a recurring problem for you, you could put the SELECT under
EXECUTE in the function.  But most likely this is just a one-time
problem.

Is there any way to clear the  cached plan manually other than
disconnecting (With the help of some commands/Configuration settings) ?

Only as of 8.3.
