I would like to suggest an improvement to the select pg_reload_conf() function.
Currently this will only return true or false indicating if reloading was successful.
I think it would be a "nice-to-have" if the function would also return the GUCs that have been changed, similar to what is being written to the logfile.
To not break existing code (e.g. scripts that only expect true/false), this could be done through an optional boolean parameter (e.g. named "verbose").
Any thoughts?
