Hi,

I made some changes to postgresql.conf and I want them to take effect without having to restart the server.

I tried 

select pg_reload_conf();
/usr/pgsql-9.1/bin/pg_ctl reload

but when I do 'show all', I see no changes take effect. 

There settings I tried to change are:
-effective_cache_size 
-work_mem

Im using posgres 9.1 on Centos Linux (amazon ec2)

Thanks
