Not sure. I count 98 GUC variables currently listed in tab-complete.c,
and 162 rows in pg_settings. So listing them all would be a pretty
sizable increase (65%) in what's already an unwieldy list. I would
prefer to see some thought given to removing useless entries ... eg,
I doubt anyone needs tab completion for "trace_notify" or "wal_debug".
However, if you favor a "no thought required" approach, listing 'em
all is certainly the path of least resistance. I'm just dubious that
that maximizes the usefulness of tab completion.
