--------------------------------
Summary: Restore to correct memory context after free query
resource in ExecutorEnd
Key: HAWQ-666
URL: https://issues.apache.org/jira/browse/HAWQ-666
Project: Apache HAWQ
Issue Type: Bug
Components: Core
Reporter: Ruilong Huo
Assignee: Lei Chang
In ExecutorEnd, we need to restore to correct memory context after free query
resource. There are two memory context based on PG_TRY of mppExecutorFinishup:
1. If mppExecutorFinishup completes successfully, the correct memory context is
estate->es_query_cxt
2. If mppExecutorFinishup errors, the correct memory context is ErrorContext
Current implementation use estate->es_query_cxt for both situation. We need to
fix this as it may lead to core dump during memory context cleanup afterwards.
