I did some investigations. The current implementation, the update plans of
different partitions use the same param id for the subplan param, but they
correspond to different SubPlanStates during execution, SubPlanState are
generated during ExecInitSubPlan and linked to ParamExecData->execPlan.
Since the plans of multiple partitions share one Param, according to the
execution order, the final execPlan will be set to the SubPlanState of the
last partition in the InitPlan phase.
And because the order of joins in different partition plans is different,
the final SubPlanState->args does not match the expectation (some are
OUTER_VAR, some are INNER_VAR), and an error is occurred (failed assertion
if "--enable-cassert" and coredump)
