In particular, have you looked at CVS tip contrib/auto_explain? It seems like you are duplicating a lot of what that can do. If that needs some additional features, you could work on that. From the big picture standpoint I think it makes a lot more sense to add instrumentation server-side than client-side. Any features you add client-side are only available to ecpg users, and you have to cope with ensuring there's a way to collect the data out of the application (which may be running in an environment where that's hard). regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
