You could try show command (http://www.postgresql.org/docs/9.3/static/sql-show.html) and see if the changes have taken effect. Usually there are comments against each parameter which mention if a restart is required. Example, port = 5432 # (change requires restart)

I changed a few logging parameters on our 9.1 server (e.g. log_rotation_age, log_rotation_size, log_min_messages). After a reload, the logging behavior has not changed. Is a restart required for these? The documentation doesn't indicate that it is.
