Dear Shlok, ``` -- Can set synchronized_standby_slots to a non-existent slot name. ALTER SYSTEM SET synchronized_standby_slots='missing'; SELECT pg_reload_conf();
-- Reset the GUC. ALTER SYSTEM RESET synchronized_standby_slots; SELECT pg_reload_conf(); ``` pg_reload_conf() is called twice here but I'm not sure it is really needed. ALTER SYSTEM itself can validate parameters via parse_and_validate_value(elevel=ERROR), and pg_reload_conf() won't affect synchronously. Also, the backend won't output even if the parameter is invalid. Best regards, Hayato Kuroda FUJITSU LIMITED
