Re[2]: [BUGS] BUG #13869: Right Join query that never ends

Greetings.

I can do more to investigate this behavior only if postgresql will consider my claim as bug that has to be fixed in
firstorder. 
Ideally  I should give my DB schema and dump or VM wich reproduces this bug, but I can not give away our internal data.
Allother options I can not describe at public mailing list. 

> So, typically the first thing to do is run "EXPLAIN"
Explain Analyze do not return any result as select query.
So this is just an explain output
