Crap, yes. That was it. Just curious about one thing: That query is part of a function. If i raise set_join_collapse in a psql bash session, and then excecute the function, there is no changes. But if i excecute the query directly in the psql session, it flys. So, what happens, when a plsql function is excecuted, it takes is own enviroment variables, or something like that?
