One issue of the base backup function is that the operation will
be a long transaction. So, non-transactional special commands,
as like as VACUUM, would be better in terms of performance.
For example, CREATE or ALTER REPLICATION.

Of course, function-based approach is more flexible and
less invasive to the SQL parser. There are trade-offs.
