Hello
I propose a enhancing of EXPLAIN statement about possibility get a plan of
other PostgreSQL process. With some other enhancing this technique can be
interesting for monitoring long duration queries.
Notes, comments?
Regards
Pavel Stehule

Does this mean that you want to track plan (and other info Explain
provides) of statements running in particular backend?
Could you please explain this in bit more detail w.r.t how this will work?

for 9.5 I plan to implement a plain EXPLAIN only. Any other improvements
can be append incrementally.
