Are there any settings in postgresql.conf that would make it unsafe to
use -m immediate?

Two concerns:

-Clients will be killed without any review, and data related to them lost

-The server will have to go through recovery to start back up again, which could potentially take a long time. If you manage a successful shutdown that doesn't happen.

Shouldn't be unsafe, just has those issues.
