databases usually provide only synchronous client libraries
Most databases have async mode available in their clients.
e.g. postgresql's libpq has PQsetnonblocking()
For the ones that don't have that available via the official clients,
people have often written alternative client libraries.
- PostgreSQL allows at most one async query in flight. Which doesn't
make it truly asynchronous. Not in the context being discussed, at least.
- MySQL does not have a maintained asynchronous client library.
libattachsql is abandonware, and the new X protocol is a completely
different story.
So no, life is not as simple as it may sound.
