Can you please take a look at the golang documentation for session leaks and give your LGTM?

| The most common reason for session leaks in the Golang client library are: | ||
| 1. Not stopping a `RowIterator` that is returned by `Query`, `Read` and other methods. Always use `RowIterator.Stop()` to ensure that the `RowIterator` is always closed. | ||
| 2. Not closing a `ReadOnlyTransaction` when you no longer need it. Always call `ReadOnlyTransaction.Close()` after use, to ensure that the `ReadOnlyTransaction` is always closed. | ||
| 3. Not closing a `BatchReadOnlyTransaction` when you no longer need it. Always call `BatchReadOnlyTransaction.Close()` after use, to ensure that the `BatchReadOnlyTransaction` is always closed. |

For a different PR: We should change the implementation of BatchReadOnlyTransaction to not use any sessions from the pool, and instead create a separate session.

BatchReadOnlyTransaction already creates its own session and do not use any sessions from the pool. Sorry for the confusion.
I have removed this line.
