> By definition, file count of a hash table should be equal to or a multiple of the bucket number of the table. So if mismatch happens, we should not treat it as hash table in data locality algorithm.
> The default behaviour should LOG_ERROR and tell the user "file count is not in proportion to bucket number for hash table with oid=XXXXX. Some data maybe lost, if you still want to continue the query, set GUC assign_randomly_for_mismatched_hash_table to true and try again."
> If GUC assign_randomly_for_mismatched_hash_table is on, the behaviour changed to treat the hash table as random table in data locality algorithm.
