Yeah, I was noticing that myself while testing pg_stat_statements.
I agree that we should fix it to reduce the message level for reloads
occurring in child processes.  I'd suggest using DEBUG2 if
(IsUnderPostmaster && process_shared_preload_libraries_in_progress).
I'm not so enthused about eliminating messaging for 
local_preload_libraries, though.
