Hello, i've been reading the README file in the lmgr folder (in src/backend/storage/lmgr/) and i have a couple of questions about locks: - What's the difference between the Lightweight Locks (LWLocks) and the Regular locks (Heavyweight Locks)? For example, if i do a query and it needs a lock, would it be a lightweight one or a regular one?
- There are two lock methods, DEFAULT and USER. Where can I get more information about them? In the README file it says that "USER locks are non-blocking", how could this be? Thank you very much! ____________________________________________________________ http://webmail.wanadoo.es.
