The result of the query used to retrieve the WAL segment size from the backend was not getting freed in two code paths. Both pg_basebackup and pg_receivewal exit immediately if a failure happened on this query, so this was not an actual problem, but it could be an issue if this code gets used for other tools in different ways, be they future tools in this code tree or external, existing, ones.
