I was playing with Advisory locks. I opened three connections to the
database And obtained a lock with the same key. I noticed that the locks
were obtained in the order of requests. I was wondering whether the locks
are guaranteed to be First Come First Serve and can this behaviour be
relied upon.
I read the docs here
<https://www.postgresql.org/docs/current/explicit-locking.html>. But it
didn't mention anything.
Thanks a lot for your time and efforts
