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. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
