This year’s edition has been the best pgcon ever for me. Granted, it’s only my third time, but still :) As Josh said the “Hall Track” in particular was very good, and the Dev Meeting has been very effective! Extensions This time I prepared some slides to present the extension design and I tried hard to make it so that we get to agree on a plan, even recognizing it’s not solving all of our problems from the get go.

So, following previous blog entries about importing fixed width data, from Postgres Online Journal and David (perl) Fetter, I couldn’t resist following the meme and showing how to achieve the same thing with pgloader.

Yes. This pgloader project is still maintained and somewhat active. Development happens when I receive a complaint, either about a bug in existing code or a feature in yet-to-write code. If you have a bug to report, just send me an email!

This time we’re having a database where sequences were used, but not systematically as a default value of a given column. It’s mainly an historic bad idea, but you know the usual excuse with bad ideas and bad code: the first 6 months it’s experimental, after that it’s historic. *Not talking about genome orphaned sequences here, though* Still, here’s a query for 8.4 that will allow you to list those sequences you have that are not used as a default value in any of your tables:

So, if you followed the previous blog entry, now you have a new database containing all the static tables encoded in UTF-8 rather than SQL_ASCII. Because if it was not yet the case, you now severely distrust this non-encoding.

Now is the time to have a look at properly encoding the live data, those stored in tables that continue to receive write traffic. The idea is to use the UPDATE facilities of PostgreSQL to tweak the data, and too fix the applications so as not to continue inserting badly encoded strings in there.
