Issue occurs in extended query protocol mode only where every query goes through PREPARE and EXECUTE phase. First time ANALYZE is executed, a list of relations to be vaccumed is extracted and saved in a list. This list is referenced in parsetree node. Once execution of ANALYZE is complete, this list is cleaned up, however reference to the same is not cleaned up in parsetree node. When second time ANALYZE is executed, segfault happens as we access an invalid memory location. Fixed the issue by restoring the actual value in parsetree node once ANALYZE completes its execution. Fixes #4857
