@bsh98 awesome - does the current version not support contracts? Will this change work seamlessly if I've already run an export against the current version? Any idea when this PR will be ready/merged?

Thank you! No, the current version does not support contracts. And yes, this should work no problem if you've already run the current version. The PR should be ready, but unfortunately I don't have an estimate on when it will be merged. (It looks like there hasn't been much activity on this repo recently.)

Hello guys

I'm using ethereum-etl-postgres (https://github.com/blockchain-etl/ethereum-etl-postgres) to fetch contracts data, and found there are some duplicate records in the data source, is there anyone encounter the same problem?

data source is: bigquery > bigquery-public-data.crypto_ethereum.contracts

I found a duplicate records through sql below, and there are more records like this:

SELECT * FROM bigquery-public-data.crypto_ethereum.contracts WHERE address = '0x21e89b517469604e7ea9f564c45ef33d512fff9d' AND block_number = 9391097
