running database in single-user mode

HI
I am running Postgres on Fedora 14 64 bit using the following command:
> service postresql start

I would like to know how to set database to single-user mode in order to run an upgrade process on database, and return it back to regular mode when upgrade process finish.

Thanks

My bad.... -D not P please see below:

http://www.postgresql.org/docs/8.3/static/app-postgres.html

"To start a single-user mode server, use a command like

postgres --single -D /usr/local/pgsql/data other-options my_databaseProvide the correct path to the database directory with -D, or make sure that the environment variable PGDATA is set. Also specify the name of the particular database you want to work in. "

One way to do this is to shut down the server and start a single-user PostgreSQL server with the -P option included on its command line.
