Hmm.  This patch breaks a feature of pg_ctl that I am really fond of for
development.  When starting a node which enters in recovery, I sometimes
use Ctrl-C to stop pg_ctl, which automatically makes the started
Postgres instance to stop, and this saves more strokes.  With your
patch, you don't get that anymore: when issuing Ctrl-C on pg_ctl then
the started instance still runs in the background.  I would be ready to
accept a patch which does not change the default behavior, and makes the
deamonization behavior activated only if an option switch is given by
the user, like -d/--daemon.  So I am -1 for what is proposed in its
current shape.
