I repeated Tony's result (Win32):

Welcome to psql 8.1RC1, the PostgreSQL interactive terminal.

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

test=# select setting from pg_settings where name = 'constraint_exclusion';
 setting
---------
 off
(1 row)

test=# select pg_reload_conf();
 pg_reload_conf
----------------
 t
(1 row)

test=# select setting from pg_settings where name = 'constraint_exclusion';
 setting
---------
 off
(1 row)

test=# LOG:  received SIGHUP, reloading configuration files

test=# select setting from pg_settings where name = 'constraint_exclusion';
 setting
---------
 off
(1 row)

test=# select setting from pg_settings where name = 'constraint_exclusion';
 setting
---------
 on
(1 row)


-- Seems that's due to delay of process SIGHUP ...
