Hi,
The GucContext of synchronous_standby_names and hot_standby_feedback
is PGC_SIGHUP, so the following should be added into the explanations about
those parameters. Attached patch does that.
---------------------
This parameter can only be set in the <filename>postgresql.conf</>
file or on the server command line.
