The other thing that was being argued was whether rules should be
changed to act that way too, and if not whether EXPLAIN ANALYZE should
be fixed to make sure it emulates rule execution better. Personally
I'd be in favor of changing rule execution and leaving EXPLAIN ANALYZE
alone, though I'm not sure if that position can command a consensus.
I seriously doubt that there are many applications out there that are
actually depending on this aspect of rule execution; if anything, there
are probably more that will see it as a bug.
Changing EXPLAIN ANALYZE seems a bit less likely to break things for
anyone depending on current behavior; but, on the other hand, it seems
there's a broad consensus that the best thing to do about rule
execution is deprecate it, so maybe it doesn't really matter.
I'm having a hard time imagining that anyone would depend on a behaviour
like this.
