stop mode shuts down the server that is running in the specified data
directory. Three different shutdown methods can be selected with the -m
option. “Smart” mode disallows new connections, then waits for all
existing clients to disconnect. If the server is in hot standby,
recovery and streaming replication will be terminated once all clients
have disconnected. “Fast” mode (the default) does not wait for clients
to disconnect. All active transactions are rolled back and clients are
forcibly disconnected, then the server is shut down. “Immediate” mode
will abort all server processes immediately, without a clean shutdown.
This choice will lead to a crash-recovery cycle during the next server
start.
