Re: Possible request for new feature

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

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