Hi! Thank you for the work with this subject.

I looked at your patch and noticed that this part of the code is repeated several times:

if (nesting_level == 0)
    {
        if (!IsParallelWorker())

            current_query_sampled = pg_prng_double(&pg_global_prng_state) < pgss_sample_rate;

        else
            current_query_sampled = false;

    }

I think you should put this in a function like update_current_query_sampled. I've attached a diff file with the changes.

Agree, thanks.
