Hello,
I don't really understand what is going on there, the result appears incorrect to me. The following page seems to offer some explanations as to what is happening: http://sql-info.de/postgresql/postgres-gotchas.html#1_6 . Indeed, adding OFFSET 0 to the "s" subquery solves the issue. Can somebody shed some light on this topic? Is this behaviour correct or should it be considered a bug?
See here for explanation: http://www.postgresql.org/message-id/8569.1128439...@sss.pgh.pa.us
Thanks! Etienne
