Hi!
Overall solution looks good for me except SQL Commenter - query instrumentation
with SQL comments is often not possible on production systems. Instead
the very often requested feature is to enable tracing for a given single query ID,
or several (very limited number of) queries by IDs. It could be done by adding
SQL function to add and remove query ID into a list (even array would do)
stored in top tracing context.
Great job, thank you!
