Preversely, if the database has no transactions then your technique is indeed safe. Likewise if you don't use the sequence inside a transaction -- but if you do have them and want to use them, odds are you'd like to be able to use the sequence with them :-)

I'm using SQLite for development and will possibly move to Oracle for production. SQLite is fine for applications that are not heavily multiuser: locking certainly exists, it's just not very finely-grained. (There are of course other limitations, like how putting the database on NFS is a bad idea, but for my purposes they don't present a problem.)
