It strikes me that the server shouldn't ever get a couple minutes behind
on writing dirty buffers; this seems more like a bgwriter configuration
issue than pg_ctl's fault.  Consider that in a standard Unix
configuration you will get about 20 seconds between SIGTERM and SIGKILL
when init wants to shut you down ...
