* NOTES
* this is the "main" module of the postgres backend and
*
* Also note: it's best not to use any signals that are SIG_IGNored in
* the postmaster. If such a signal arrives before we are able to
- * change the handler to non-SIG_IGN, it'll get dropped. If
- * necessary, make a dummy handler in the postmaster to reserve the
- * signal.
+ * change the handler to non-SIG_IGN, it'll get dropped. Instead,
+ * make a dummy handler in the postmaster to reserve the signal.
+ * (Of course, this isn't an issue for signals that are locally generated,
+ * such as SIGALRM and SIGPIPE.)
