The point of Marti's comment was that the estimates (as presented by
EXPLAIN PLAN FOR in Oracle) are inherently imprecise. Don't trust what
Oracle is telling you about the expect
For security reasons, I cannot put real-time senario into loop,
the one which I gave is an example, if I have solution for this then
same will be applied for real-time senario
We have implemented PARALLEL technology into our database and same
expecting after migration to PostgreSQL,

Yes
"Hint method" is an alternative solution which does not appear to be
exclusive parallelism solution as it is included in comment block and have
no error handling,
and this could be one of the reason against PG policy
"Parameter method" ( which we are thinking about ) can be very exclusive
