Use a transaction and lock the source table first.
BEGIN TRANSACTION;
LOCK TABLE src_table;
INSERT INTO dest_table SELECT * FROM src_table
WHERE ...;
DELETE FROM src_table WHERE ...;
COMMIT TRANSACTION;
No other backend can add, modify or remove rows to/in/from
src_table while you have a lock on it.
