Обсуждение: pgsql: Fix possible infinite loop with Parallel Append.

Fix possible infinite loop with Parallel Append.

When the previously-chosen plan was non-partial, all pa_finished
flags for partial plans are now set, and pa_next_plan has not yet
been set to INVALID_SUBPLAN_INDEX, the previous code could go into
an infinite loop.
