PL/Python vars are freed when the interpreter instance is freed and their refcounts reach zero. I believe we use one subinterpreter for the lifetime of the backend session. It might be worth checking whether we do an eager refcount check and sweep when a procedure finishes. But in general, I suggest that relying on object finalizers/destructors to accomplish side effects visible outside the procedure is bad development practice. Instead, use a "with" block, or a try/finally block, and do explicit cleanup for external resources. -- Craig Ringer http://www.2ndQuadrant.com/ 2ndQuadrant - PostgreSQL Solutions for the Enterprise
