Homer pulls DuckDB’s CGO stack through **`github.com/duckdb/duckdb-go/v2`**, which depends on the prebuilt static libs in **[`github.com/duckdb/duckdb-go-bindings`](https://github.com/duckdb/duckdb-go-bindings)** (see that repo for versioning, e.g. DuckDB `v1.5.4` → module tag **`v0.10504.0`**).

By default **`src/go.mod` contains a `replace` directive** pointing to a fork that eliminates per-string CGO malloc/free in the Appender hot path (visible as `VectorAssignStringElementLen` + `duckdb_free` per-column in profiles). This fork has been benchmarked against upstream and showed a measurable reduction in CGO overhead at high PPS.
