Are you speaking of the logging_collector GUC? I think the difficulty
is - if you wanted to turn this on without a restart, how would you
get the collector's stdin to be each backend's stdout/stderr? I don't
see any way to do it, actually.
This is probably blasphemy, but "off" would log to a symbolic link
pointing to /dev/null, which is repointed to a log_file if reloaded
with "on"?
No, off simply means we aren't collecting the log, not that we aren't
producing any. All the buildfarm tests run without using the logging
collector, but they DO produce logs :-)
What's the use case for making it settable on the fly? I can't see that
this is worth the probably quite large amount of coding that would be
required.
