No objections from here to change the signal handlers.  Still, I would
like to understand why the bootstrap process has been signaled to
begin with, particularly for an initdb, which is not really something
that should happen on a server where an instance runs.  If you have a
too aggressive monitoring job, you may want to revisit that as well,
because it is able to complain just with an initdb.

  1. In bootstrap mode, use default signal handling for SIGINT etc.
