When the logical decoding restarts from NEW_CID, since there is no association between the top transaction and its subtransaction, both are created as top transactions and have the same LSN. This caused the assertion failure in AssertTXNLsnOrder(). This patch skips the assertion check until we reach the LSN at which we start decoding the contents of the transaction, specifically start_decoding_at LSN in SnapBuild. This is okay because we don't guarantee to make the association between top transaction and subtransaction until we try to decode the actual contents of transaction. The ordering of the records prior to the start_decoding_at LSN should have been checked before the restart. The other assertion failure is due to the reason that we forgot to track that we have considered top-level transaction id in the list of catalog changing transactions that were committed when one of its subtransactions is marked as containing catalog change.
