To expand on other responses, try "select * from pg_settings;" and see
http://www.postgresql.org/docs/current/static/view-pg-settings.html

Anything with a "context" of "postmaster" requires a restart so while
shared_buffers requires a restart the other three do not and, in fact,
can be set by a user on a per-connection basis.
