Postgres storage requirements of sepolia and base sepolia are high

[rdx4499]

I am not sure if its a bug or not but I have deployed three same subgraph on thee different testnetwork sepolia, base sepolia and pulsechain testnet. I have only done single transaction on both seplia network, for this postgres database size is 17 GB each , and for pulsechain testnet I have done thousands of transaction but it only takes 377 MB. Below is my docker compose file with network configuration

How can I reduce the database size ?
