I need to make changes to these settings in postgresql.conf:
* effective_cache_size
* shared_buffers
* work_mem
* maintenance_work_mem
On a live, production server, can I simply do a "reload" and get those
values in, or do I need to do a stop/start?
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.
