Hi,
I tried the patch, here my comment:
> gettext_noop("Zero effective disables sampling. "
> "-1 use sampling every time (without limit)."),
I do not agree with the zero case. In fact, sampling is disabled as soon as
setting is less than log_min_duration_statements. Furthermore, I think we should
provide a more straightforward description for users.
I changed few comments and documentation:
* As we added much more logic in this function with statement and transaction
sampling. And now with statement_sample_rate, it is not easy to understand the
logic on first look. I reword comment in check_log_duration, I hope it is more
straightforward.
* I am not sure if "every_time" is a good naming for the variable. In fact, if
duration exceeds limit we disable sampling. Maybe sampling_disabled is more clear?
* I propose to add some words in log_min_duration_statement and
log_statement_sample_rate documentation.
* Rephrased log_statement_sample_limit documentation, I hope it help
understanding.
Patch attached.
