Configure prover

Configure prover DB

1. Copy/paste the following script into ~/zkevm/mainnet/db/scripts/init_prover_db.sql to replace what’s there.

   CREATE DATABASE prover_db;
   \connect prover_db;
   
   CREATE SCHEMA state;
   
   CREATE TABLE state.nodes (hash BYTEA PRIMARY KEY, data BYTEA NOT NULL);
   CREATE TABLE state.program (hash BYTEA PRIMARY KEY, data BYTEA NOT NULL);
   
   CREATE USER prover_user with password 'prover_pass';
   GRANT CONNECT ON DATABASE prover_db TO prover_user;
   ALTER USER prover_user SET SEARCH_PATH=state;
   GRANT ALL PRIVILEGES ON SCHEMA state TO prover_user;
   GRANT ALL PRIVILEGES ON TABLE state.nodes TO prover_user;
   GRANT ALL PRIVILEGES ON TABLE state.program TO prover_user;
   

2. Save and exit the file.
