Новое развитие LUI (Live Universal Interface) - LUI4ORA2PG, инструмент миграции

The report will talk about a new tool for migrating application systems from the Oracle environment to the Postgres environment. The tool is developed on the basis of the ora2pg tool (by Gill Darold) and the domestic LUI application development tool. Talks on LUI were given at past PGConfs in 2019 and 2020:

Ivan will explain the philosophy behind this enhanced variant of PostgreSQL, reveal the differences between Postgres and Postgres Pro and provide the roadmap for the further evolution of Postgres Pro DBMS.

Multicorn Foreign Data Wrapper против plpython

Multicorn technology allows you to develop FDWs in Python, which is much easier and faster than creating FDWs in C. However, there is a downside, Multicorn FDWs work well with primitive WHERE conditions, but more complex cases cause difficulties, which I will talk about. Cases will be considered on the example of my Multicorn FDW for getting OpenStreetMap data. I will also show examples of using the same code in Multicorn FDW and plpython functions, including performance comparison. In conclusion, I will share my findings on when it is better to use plpython, and when Multicorn FDW is more preferable.

Python для PostgreSQL: как его использовать и преуспеть в этом?

Let's see, with practical examples, how to make Python and PostgreSQL talk to each other seamlessly: how to connect to a server, how to exchange data, manage transactions, passing parameters in a safe and expressive way, how to manage notifications.

We will cover psycopg2, the most used PostgreSQL adapter for Python, but also look and the up and coming psycopg3: what will remain the same, what will change, how to better organise a Python program to make the most of PostgreSQL.
