Actually this is possible without moving to part of core, too -- change
things so that putting it in shared_preload_libraries reserves the shmem
area but does not enable collection, then have a separate GUC that
enables/disables collection. A bit like archive_mode=on,
archive_command=/bin/true, which allows to change archive_command
without restarting.
