>> Because you are creating (specific) objects.
I have gone through the link and how would i figure out which specific object is causing this. Can you please elaborate more here.
We do not have the much temporary table usage.
Since the size is bigger (5 GB) to maintain. does it requires maintenance as well for the pg_class.
It seems its affecting performance.

PostgreSQL 9.4.0
Are generalizing here or are you really running 2+ year old patch version?
Why pg_class table is getting bigger in size.
Because you are creating (specific) objects.
How to stop increasing it.
Stop creating (those specific) objects.
Does it affect the performance.
It can - depends greatly on scale.
Note, frequent usage of temporary tables is a common cause for this kind of behavior.
