After having been involved in many migration projects over the last 10 years, I decided to publish the following White Paper in order to share my learnings.

The paper is titled Migrating to PostgreSQL, Tools and Methodology and details the Continuous Migration approach. It describes how to migrate from another relational database server technology to PostgreSQL. The reasons to do so are many, and first among them is often the licensing model.

Last week I had the pleasure to present two talks at the awesome PostgreSQL Conference Europe. The first one was actually a tutorial about Writing & using Postgres Extensions where we spent 3 hours on what are PostgreSQL Extensions, what you can expect from them, and how to develop a new one. Then I also had the opportunity to present the new version of pgloader in a talk about Migrating from MySQL to PostgreSQL.

In our previous article about Loading Geolocation Data, we did load some data into PostgreSQL and saw the quite noticable impact of a user transformation. As it happens, the function that did the integer to IP representation was so naive as to scratch the micro optimisation itch of some Common Lisp hackers: thanks a lot guys, in particular stassats who came up with the solution we’re seeing now.
