Hi

I like the idea of sampling slow statements via  log_statement_sample_rate.
But I miss some parameter that can ensure so every query executed over this
limit is logged.

Can we introduce new option

log_statement_sampling_limit

The query with execution time over this limit is logged every time.

What do you think about this?

Regards

Pavel
