@electrum I couldn't find any existing unit tests that directly invoke finishMerge. Is there another place or approach I should use to test this change?

[cpcloud]

Ok, grepping around I found testing/trino-product-tests/src/main/java/io/trino/tests/product/hive/TestWriteToHiveTransactionalTableInTrino.java which looks like it might be the place to add a test for this.
