There are very few things that one can change in a FreeBSD system that
will _require_ a restart or a shutdown to single user mode: kernel
modifications and updates or a decrease in the securelevel of the
system, are the only ones I can think of right now.

The rest of the changes you make to rc.conf usually correspond to
something that can also be changed using the available tools, without
a reboot.

To stop a service, just run /etc/rc.d/service stop.

To start one, /etc/rc.d/service start.

To change the keyboard rate, run: kbdcontrol -r newrate

To load a console font, vidcontrol -f 8x16 newfont

etc... you get the idea by now.

To get back to the original poster's question, postgres installs a
startup script in `/usr/local/etc/rc.d'.  You can start the postgres DB
server process, by:

	# /usr/local/etc/rc.d/010.pgsql.sh start

If this is the first time you're installing a PostgreSQL database, it's
probably a good idea to read the PostgreSQL manual too.  It's an
excellent read and you will find a lot of useful stuff in there to tweak
the setup of your database and shape it the way you want it to be.
