pg_ctl failed when I added a thirteenth parameter (log_temp_files).  Is this documented, and I missed it?

(The purpose is to optimize for a 30-thread pg_restore of a multi-TB 9.6 database.  Once it's finished, I stop/start, to enable "production" values like fsync=on.)

pg_ctl restart -wt999 -mfast
          -o '-c fsync=off' \
          -o '-c full_page_writes=off' \
          -o '-c log_statement=none' \
          -o '-c log_temp_files=100kB' \
          -o '-c max_wal_size=36GB' \
          -o '-c wal_level=minimal' \
          -o '-c max_wal_senders=0' \
          -o '-c wal_buffers=64MB' \
          -o '-c log_checkpoints=off' \
          -o '-c autovacuum=off'
pg_ctl: too many command-line arguments (first is "restart")

Arguments are not parameters.  Try putting the restart argument after all parameters.

Also, you are missing a line continuation backslash so you actually only supplied three arguments, where only 1 is accepted.
