The ztsd needs to be version bumped, to be consistent with dgraph, and more specifically use the patched version [v1.4.5+patch2](https://github.com/DataDog/zstd/tree/v1.4.5%2Bpatch2) in both badger and dgraph.

> The semantic versioning of this release is a bit particular since it only includes changes in the Go wrapper without any changes from the upstream C repository ([https://github.com/facebook/zstd/releases](https://github.com/facebook/zstd/releases)).
> 
> Changes:
> 
> - Pass pointers to C as unsafe.Pointer, not uintptr (memory corruption) [@evanj](https://github.com/evanj) ([#91](https://github.com/DataDog/zstd/pull/91))
> - Add go.mod file [@Viq111](https://github.com/Viq111) ([#94](https://github.com/DataDog/zstd/pull/94))
> - [circleci] Fix 32 bits builds [@Viq111](https://github.com/Viq111) ([#92](https://github.com/DataDog/zstd/pull/92))
> 
> This is a recommended version as it fixes a potential memory corruption bug when the system is under-pressure (memory and/or lots of threads) which forces the Go runtime to move the stack around.
