+1, we should call it "dumb" :)
Not accepting new connections with "the database system is shutting
down" makes it even worse -- it means you can't log in to the server
to inspect who's querying it or call pg_terminate_backend() on them.
I couldn't find any past discussions about changing the default to "fast".
Are there any reasons why that cannot be done in a future release?
Regards,
Marti
