Re: Buffers option

[hmidi slim <hmidi.slim2@xxxxxxxxx>]

with this query:

explain (ANALYZE,BUFFERS) SELECT p.*
FROM place as p, user as u where p.id = u.place_id

and to_tsvector('simple', p.name) @@ to_tsquery('simple', 'a:*') and u.status = true;

I got the buffers.I think that is not working with JOIN INNER.

Not sure but I see a lot of nodes 'never executed' and 'rows=0' on the
first loop. Could it be the optimzer did not execute nothing at all?
