Is create_pool() function async?

[AptRoApt]

I've looked at the sources and there are two functions: async _create_pool() and common create_pool(). Which one should I use?
The documentation uses "await create_pool()" but I can't understand why there is "await" keyword and is it asynchronous.

Not only this!

The create_pool function returns a _PoolContextManager instance instead of a Pool one.
