Re: Possible request for new feature

Tom,
Thanks so much. That was very useful. It is more useful than my suggested enhancement.

Thanks,

A nice feature would be the ability to do something just like EXPLAIN ANALYZE on queries with the slight difference of actually returning the results from the query and appending the QUERY PLAN to the end of the query.

Such a behavior would break just about every client application. Have you looked into using the auto_explain module, which instead logs query plans to the postmaster log? That's a far less invasive way of collecting plans for queries of live applications. pg_stat_statements would be worth a look too.
