# Week15 My work on upgrading the [Slasher database](https://github.com/sigp/lighthouse/pull/8084) is virtually completed (aside the comments/feedback from my mentor which I have fixed). ## PostgresDB I continued with my work on implementing a [PostgresDB backend for Lighthouse’s Beacon Node](https://github.com/sigp/lighthouse/pull/8157). With more insight from my work on [upgrading Redb](https://github.com/sigp/lighthouse/pull/7917) and [Slasher database](https://github.com/sigp/lighthouse/pull/8084#pullrequestreview-3286545367), I have more understanding of my work on the implementation for postgres. Did some basic integration of`PostgresDB` into the `DatabaseBackend`, allowing `lighthouse` to select `postgres` as a backend at runtime. ### Next Steps Start wiring Postgres into higher-level Beacon Node components for end-to-end runs.
