Postgres 9.6 reload or restart after config changes I need to change a couple of log config settings in postgresql.conf. How do I know which parameters need a restart or reload?

Is there a list of parameters that need a restart?
Try this query:

SELECT name, context
FROM pg_settings
WHERE name ilike '%log%';


The pg_settings view gives the context for any setting. sighup is a reload and postmaster is a restart.
