PostgreSQL v11 offline (portable) version libwinpthread-1.dll error

I downloaded offline version of PostgreSQL v11 unpacked and run the code 

pg_ctl --help. 

It gave an error, wanted libwinphread-1.dll 

Downloaded that library from https://osdn.net/projects/sfnet_sixtyfourbitcompiles/downloads/64bit/libwinpthread-1.dll/

Now it works!!!

Please update (or what else needs to be done) in order to use offline version of PostgreSQL v11.

Thank you very much for your product

Your Sincerely
