From f8dd4ecb0b7fc3420e199021375e622815cd326f Mon Sep 17 00:00:00 2001 From: Andres Freund Date: Thu, 5 Aug 2021 12:17:31 -0700 Subject: process startup: Remove bootstrap / checker modes from AuxProcType. Neither is actually initialized as an auxiliary process, so it does not really make sense to reserve a PGPROC etc for them. This keeps checker mode implemented by exiting partway through bootstrap mode. That might be worth changing at some point, perhaps if we ever extend checker mode to be a more general tool.
