Hi folks.

Is there any restriction in create and start threads inside Postgres? 

I'm trying to develop a multithread planner, and some times is raised a exception of access memory.

I'm debugging the code to see if is a bug in the planner, but until now, I still not found. I tried to use the same memory context of root process and create a new context to each new thread, but doesn't worked.

Any tips?
