Funny, we were just discussing this at OpenDBCon. Seems that you can't do a
full implementation of MERGE without Predicate Locking (the ability to say
"lock this table against inserts or updates of any row with key=5").
However, Peter suggested that we could do a proof-of-concept implementation,
working out syntax and trigger issues, based on a full table lock and do the
hard work once it was proved to be feasable.
Peter?
