That seems to be it:

# psql regression
Welcome to psql 7.3.2, the PostgreSQL interactive terminal.

Type: \copyright for distribution terms
\h for help with SQL commands
\? for help on internal slash commands
\g or terminate with semicolon to execute query
\q to quit

regression=# \c template1
You are now connected to database template1.
template1=# create user testuser password 'pw' nocreatedb nocreateuser;
CREATE USER
template1=# create database testdb owner testuser encoding 'utf-8';
CREATE DATABASE
template1=# \c testdb testuser
You are now connected to database testdb as user testuser.
testdb=> update pg_settings set setting='public' where name='search_path' ;
ERROR: pg_settings: permission denied
