Ignore interrupts during quickdie().
Once the administrator has called for an immediate shutdown or a backendcrash has triggered a reinitialization, no mere SIGINT or SIGTERM shouldchange that course. Such derailment remains possible when the signalarrives before quickdie() blocks signals. That being a narrow raceaffecting most PostgreSQL signal handlers in some way, leave it foranother patch. Back-patch this to all supported versions.
