How To Install python3-django-pglocks on Ubuntu 22.04
Introduction

on Ubuntu 22.04.
What is python3-django-pglocks
python3-django-pglocks is:
django-pglocks is a context manager for Django. Advisory locks are application-level locks that are acquired and released purely by the client of the database; PostgreSQL never acquires them on its own. They are very useful as a way of signalling to other sessions that a higher-level resource than a single row is in use, without having to lock an entire table or some other structure.
It’s entirely up to the application to correctly acquire the right lock.
Advisory locks are either session locks or transaction locks. A session lock is held until the database session disconnects (or is reset); a transaction lock is held until the transaction terminates.
Currently, the context manager only creates session locks, as the behavior of a lock persisting after the context body has been exited is surprising, and there’s no way of releasing a transaction-scope advisory lock except to exit the transaction.
This package contains the Python 3 version of the library.
