PGConf.SPB 2023

Recently, one of the most common migration methods has become migration using the free ora2pg tool. However, many note the extremely low performance of this tool, especially when it comes to databases of 1 Terabyte and above. This presentation describes how to significantly speed up database migration using oracle_fdw alone or in combination with ora2pg.

In this brief overview presentation we will discuss Postgres Pro Enterprise Manager (PPEM) capabilities, and how it helps DBAs to be more productive.

Unfortunately, ideal computer systems exist only in science fiction books. PostgreSQL is not exception and sometimes problems may occur. I would like to discuss how to correctly (and incorrectly) try to solve a problem, which way to choose, which tool to use.

The talk is of interest to both beginners and experienced users and database administrators.

A story about practical approaches and tools for automating migration using 2 examples: a database with a structure change in the new version and a database with a significant content of the application's business logic.
