Products.ZPsycopgDA
=====================
This is a Zope database adapter for PostGreSQL based on psycopg2__ for Zope 4
and up on all Python versions supported by Zope 4 and 5.
The code was forked from the original project at
https://github.com/psycopg/ZPsycopgDA because it appears to be dead. The old
code is not compatible with Zope 4/5 and Python 3.

Changelog
=========
4.3 (2025-10-07)
----------------
- Ensure connections always reconnect deterministically after a server
disconnect (or crash).
Previously the pool may have harboured long-running connections that only
got reconnected when the pool felt like returning it to the application.
Those connections can easily have lingered for a long time, causing
user-visible errors long after the original problem was fixed, e.g. when
the server has restarted a couple of hours ago.
(`#7 <https://github.com/dataflake/Products.ZPsycopgDA/pull/7>`_)
- Add support for Python 3.13.
- Drop support for Python 3.7 and 3.8.
4.2 (2023-12-07)
----------------
- Add support for Python 3.12.
- Ensure connection always get properly initialized.
- Add support for PostgreSQL 13.
4.1 (2023-10-04)
----------------
- Add support for reading the connection string from an environment variable.
Use ``ENV:DB_CONN`` as connection string to look up the actual connection
string in the environment variable ``DB_CONN``.
4.0 (2023-02-02)
----------------
- Drop support for Python 2.7, 3.5, 3.6.
3.1 (2023-01-16)
