1.18 typing violation

[mhanberg]

Description

I haven't looked into this much, but dropping the issue before i forgot.

When compiling explorer in CI for 1.18.2, the typing warning was emitted

     warning: the following clause will never match:
         {:ok, df}
     because it attempts to match on the result of:
         from_query(conn, query, params, opts)
     which has type:
         none()
