Postgres autovacuum, bloat and tpc-c style workloads

For most workloads the Postgres Autovacuum daemon works just fine. You go about your day with 3 workers that wake up once a minute to make sure that everything is nice and tidy. If things are dirty enough (around 10%) then one of the workers gets in gear and cleans things up. Unfortunately, if you have an inverted load from the norm, Autovacuum may not be able to keep up …

Where is the Postgres community?

A recent poll was conducted @amplifypostgres to determine where the Postgres community should have its interactive communication. Options included were Google Hangouts, Slack, Reddit or “Other”.

The results were not surprising, with Google Hangouts beating Slack with 157 votes cast. There were also notable mentions of IRC, and Gitter. A couple of long time Postgresql.Org members asked the inevitable, “What is wrong with IRC?” Of course there is nothing …

PostgreSQL: The Center of your Data Universe @ Datalayer Conference

You should always be careful of what you ask for. A couple of months ago while I was feeling particularly brave, I submitted to present at the DataLayer Conference. The next thing I knew, I was speaking at the DataLayer Conference. The conference takes place in Austin on May 17th. Conferences like this one are an awesome channel for PostgreSQL advocacy. Of course I am partial to PgConf US but …

Indirect Advocacy

Last week I spoke at the Bellingham Young Professional Group on starting and running a business. It was a well attended presentation. I was nervous at first because although I do a lot of public speaking, I usually speak to technical people. This was a wholly different crowd and I was pulling from a different set of expertise. The crowd was largely under 30 and wanting to start a business …

PostgreSQL for Oracle people

Below is the video of the webinar I did recently on PostgreSQL and Oracle. This webinar went very well. This is the first time I had ever performed a webinar that I recall. It was an interesting experience.

Do not buy the closed source lie of free videos

There is a nice lie out there. A lot of people want to believe it. They think by believing this lie it will somehow increase something for them. In some ways that is true. If you want what you are doing to be about you. If you are a believer in Open Source, it isn't about you. It is about the community and bettering that community as a whole …

What should I submit to PgConf US 2017?

From the title, that is the question. This is the last week of the PgConf US 2017 CFP (you can submit here: http://www.pgconf.us/2017/submit/) and I have no idea what to submit.

I am blessed that my talks are very well attended, the audience is engaged and we all have a good time. Many times laughing at me because I have a hard time staying …

Can I make initdb quiet?

A #postgresql user today asked:

noob question - trying to write a Dockerfile that runs postgres... how do I get the effect of a non-interactive `service postgresql initdb` call?

 
While several other community members provided the truthful but not helpful answer of, "Just throw Docker in the Trash", I worked out the following hack/trick/snipe hunt. The answer is, you can't. You have to call initdb directly. This …

psql tips: Change the location and filtering of the history file

Anyone who uses PostgreSQL knows of the best client available: psql. This is the client that ships with PostgreSQL. Yes it is a command line client (which turns some people off) but that also means that it is the most efficient at everyday tasks for a DBA. What a lot of people don't know is that psql is rather configurable. Here is an example:

Problem 1: I want my …
