Hi!

Please check some suggested improvements -
1) query_id added so span to be able to join it with pg_stat_activity and pg_stat_statements;
2) table for storing spans added, to flush spans buffer, for maintenance reasons - to keep track of spans,
with SQL function that flushes buffer into table instead of recordset;
3) added setter function for sampling_rate GUC to tweak it on-the-fly without restart.
