reindexing

The online docs have this to say about reindexing a whole DB:

   Rebuild all system indexes (this will only work in a standalone
   backend):

   REINDEX DATABASE my_database FORCE;

What does "standalone backend" mean? And how can I use this command to
reindex my DB? I have tried version commands but always get:

ERROR:  REINDEX DATABASE: Can be executed only on the currently open
database.

Thanks!

You run a backend manually without anything else being able to connect. See
"man postgres" for details. You'll want to shut down PG, start the backend
with -O -P flags and the database name, reindex and Ctrl-D to finish. Then,
restart PG normally.
