Description

The reasons are:

1) It is not used anymore.

2) Have seen crash due to this. The scenario is that:

The datalocality memory context on which resource_parameters is palloc-ed is reset before calculate_planner_segment_num() finishes, thus later access to resource_parameters could lead to crash or wrong results. A code path example which could lead to segfault is:

ProcessUtility()>PerformCursorOpen()>_copyPlannedStmt()->_copyQueryResourceParameters()
