"Values set with ALTER SYSTEM will be effective after the next server configuration reload (SIGHUP or pg_ctl reload), or after the next server restart in the case of parameters that can only be changed at server start."
Isn't it unfortunate that the command used for changing the configuration file from within SQL mentions SIGHUP and pg_ctl reload, but not "select pg_reload_conf();", as a way to activate that change?
