Hi everyone,
I believe we should also include this check in the pgss_ExecutorEnd()
function because sampling in pgss_ExecutorEnd() ensures that a query not
initially sampled in pgss_ExecutorStart() can still be logged if it
meets the pg_stat_statements.sample_rate criteria. This approach adds
flexibility by allowing critical queries to be captured while
maintaining efficient sampling.
I attached new version of patch.
