The columns are id, blocknumber and jsondata.
I have not been told anything ABT data retention and I will ask them.
Problem I am trying to resolve is, 30gb is big and it will be every growing always. By doing this, i am making the scan easier (despite having indexes).
Growth will be 10gb per year data.
Incase I am doing partition, Plz provide any script that does partitioning automatically. We are using postgres version 15.

In fact, you want to do manual partitioning.
Why reinvent the wheel?

What problem do you have to solve? 30 GB is not so big, but since when
do you store data? Will you purge the table? What is the main access key
of your queries (critical for the partitioning key)?
Without other information I'd say that if you never read the former
months again, partition by month, perhaps by year.
