Yep. Actually, the biggest part of this was figuring out what to do about the pg_locks view. Since that's basically decided, all that remains is to decide what if anything to do about the max_locks_per_transaction GUC variable. User locks at the very least are extra-transactional so this could perhaps be renamed. This could possibly hinge on how Alvaro's 'spill to disk' scenario plays out. FWIW, I'm a huge fan of the current behavior which is to drop transactions when running out of lock-space. In any event, I'll rewrite the interface and the documentation for user-locking with minimal changes except to expose more of the locktag structure and remove references to the deprecated and conceptually confusing oid.
