Remove the streaming files for incomplete xacts after restart.
After restart, we try to stream the changes for large transactions thatwere not sent before server crash and restart. However, we forget to sendthe abort message for such transactions. This leads to spurious streamingfiles on the subscriber which won't be cleaned till the apply worker orthe subscriber server restarts.Reported-by: Dilip KumarAuthor: Hou ZhijieReviewed-by: Dilip Kumar and Amit KapilaBackpatch-through: 14Discussion:https://postgr.es/m/OS0PR01MB5716A773F46768A1B75BE24394FB9@OS0PR01MB5716.jpnprd01.prod.outlook.com
