python3-django-pglocks - 1.0.4-2 main

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.
