right circumstances a hash join executed as a DECLARE CURSOR/FETCH query would crash the backend. Problem as seen in current sources was that the hash tables were stored in a context that was a child of TransactionCommandContext, which got zapped at completion of the FETCH command --- but cursor cleanup executed at COMMIT expected the tables to still be valid. I haven't chased down the details as seen in 7.0.* but I'm sure it's the same general problem.
