After updating pg_hba.conf or postgresql.conf, the server needs the config needs to be reloaded. The easiest way to do this is by restarting the postgres service:

service postgresql restart

When the service command is not available (no upstart on Synology NAS, for example), there are some more creative ways to reload the config. Note this first one needs to be done under the user that runs postgres (usually the user=postgres).

user#  sudo su postgres
postgres#  pg_ctl reload
