with_advisory_lock is a Ruby gem that provides a simple and thread-safe way to use PostgreSQL advisory locks within Ruby applications. It allows developers to wrap critical code sections with database-level locks to prevent race conditions across concurrent processes or threads. It’s especially useful in distributed systems, background job processing, or scheduled tasks where application-level mutexes aren't sufficient.

- Thread-safe locking mechanism for Ruby apps
