Yes, I think it's non-fatal :-)
In any production environment, you are going to be running postgresql as
a service. In that case it's not up to the console ctrl handler to
handle these events, but the service manager. Since it's not a console
program, I assume (no, haven't tested) that it will/may fail in this
cse.
And if you're just testing, you will want it to run with a warning..
Any integration with the Service Control Manager will come later.
Depending on how that it done, this might change. I suggest we revisit
it then.
Also, if we fail the console ctrl handler, the default handler will
always be used. This one will terminate the process, similar to "kill
-9" on Unix. While not the nice thing to do, the database shuold still
survive this. The events will not be totally ignored.
(And yes, I'll be getting to SIGFPE).
