# Week17

Huge milestone this week -- I was successfully booted the Lighthouse Beacon Node with the Postgres backend, reaching the `Block production enabled` stage on Holesky

## What was done
*Follow the [PR here](https://github.com/sigp/lighthouse/pull/8157)*
- Completed implementation of core `KeyValueStore` methods for Postgres:
- `open` (connection pooling, table auto-creation)
- `get_bytes`, `put_bytes`, `key_exists`, `key_delete`, `do_atomically` with proper transaction with proper transaction handling (`BEGIN ... COMMIT`)
- Wired the Postgres backend into `interface.rs` and ran `cargo test -p store --features postgres -- --test-threads=1` --all store tests, including `simplediskdb` passed.
- Integrated Postgres as a selectable backend via `--beacon-node-backend postgres`.
