There is:

http://www.postgresql.org/docs/8.1/interactive/view-pg-settings.html

You could also look in the postgresql.conf file or use the SHOW
command.

I normally use:

select name,current_setting(name) from pg_settings where
source='configuration file'

To figure out all the things that were set at initdb time from a new
running database.  You can also look at the postgresql.conf file it
generated and search for lines that are not commented out with "#" at
the start.
