Statediff database indexing

To process data in real time as Geth syncs updates to the Ethereum execution layer, the statediff service is able to directly transform and load data into a Postgres database. The indexer package contains abstractions for handling this ingestion.

Interface

A StateDiffIndexer object is responsible for inserting statediff data into a database, as well as managing watched address lists for a given database. Three implementations are currently maintained:

• sql for direct insertion to Postgres
• file which writes to CSV for SQL files for insertion in a separate step
• dump which simply dumps to stdout
