I know that's effectively an atomic action, but I'd feel a lot more comfortable reversing that logic so the delete is based on the results of the insert.

WITH saved AS (
    INSERT INTO dst
    SELECT * FROM src WHERE ...
    RETURNING *
)
DELETE FROM src
 WHERE ...;

I'll admit yours is cleaner, though. :)

That is a good idea. I didn't even realize that there was such a command, so I'll definitely use those.
