pg_reload_conf()

maybe I am missing something...

with superuser rights, on a postgres 14 and postgres 15 version:

select  setting, boot_val, reset_val from pg_settings where name='log_connections';

off off off

alter system set log_connections to 'on';

... strange

select pg_reload_conf();

t

very strange.

cat postgresql.auto.conf

log_connections = 'on'

obviously, if I stop and restart the DB,

So, I am perplexed: what pg_reload_conf() is doing/not doing ?

thanks
