Обсуждение: EXPLAIN EXECUTE

I notice that you can't explain stored plans, i.e., EXPLAIN EXECUTE.
Might be handy to have.

Yeah, that was on my to-fix list also.  There is more reason to have
this than just completeness: as things stand, EXPLAIN cannot teach you
anything about what the planner does with parameterized queries ---
which arise not only in PREPARE, but in SQL and plpgsql functions.
EXPLAIN EXECUTE would make it possible to look at parameterized plans.

Heh, I too was planning to implement this. Would you like to take a
crack it at, or should I?

Cheers,
