I think it’s not so hard to support `seekstart` in Libz.jl; just initialize the zstream object and seek the underlying IO object to the start. Can you file an issue on the repository or send us a pull request?

I would like to thank all of you who helped me, and even the ones who couldn’t but read my messages. I will try to solve this thread with JuliaDB.jl, which was just [announced](https://discourse.julialang.org/t/ann-juliadb-jl/3564). You guys were great.
