The description here seems a bit short on details to me. I would say
something like "Fraction of statements over log_min_duration_statement
to log"; otherwise it's not clear why this doesn't apply to
log_statement. I think the extra_desc should be more verbose too. (Not
really clear to me what to put in each ... suggestions welcome.)
I totally agree with that.
I like your short_desc, so I propose:
short_desc: "Fraction of statements over log_min_duration_statement to log"
long_desc: "If we only want a sample, use a value between 0 (never log)
and 1.0 (always log)"
If you agree with that, I will send another patch (I will complete
postgresql.conf.sample with the same description).
(More generally, I think we should add a lot more juice to the GUC
description fields.)
Attached is pgindent fixes for your next submission.
Thanks, (I have to remember to pgident patches before submission)
