The docs clearly answer this IMO:
If archive_command is an empty string (the default) while archive_mode is enabled, WAL archiving is temporarily disabled, but the server continues to accumulate WAL segment files in the expectation that a command will soon be provided.
Though I suppose I would argue to either remove the word temporarily or describe under what conditions, besides putting in a non-empty string, would re-enable it. Additionally, change disabled to suspended since that doesn’t contravene the behavior of an enabled archive mode to never remove WAL without a successful execution of a non-empty archive_command.
