"pg_ctl stop -m smart" will wait for all connections are disconnected and
"pg_ctl stop -m fast" will disconnect all connections forcibly.
But "fast" after "smart" also wait for disconnections.
Can we change the behavior that "fast" overwrites "smart" mode?
I'd like to achieve the following sequence:
$ pg_ctl stop
$ (found some connections remain)
$ [Ctrl+C]
$ pg_ctl stop -m fast
$ (force disconnect and stop server safely)
Regards,

+1. This behavior was supported in 8.2 or before, but broken in 8.3.
Here is the patch. This should be backported to 8.3 and 8.4.

I think this was my fault :-(. Thanks for the fix.
