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 took a …

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 …

Will Postgres use the second element of an index if it is the only element in the WHERE clause?

This is a test table from an Oracle to Postgres migration. The table has had a dozen or so columns removed for the illustration of this test case. I did not design this table but the customer is fixing it (adding proper primary key, changing to boolean and integer where appropriate etc...).

Table "public.costcenter"

Rich in the Jungle: A AWS to Softlayer comparison for PostgreSQL

I have updated my Rich in the Jungle presentation with new pricing for AWS vs. Softlayer. Things haven't changed much, in terms of raw performance per dollar (which is not the only qualifier). Softlayer is clearly the winner.

The fall of Open Source

Once upon a time FOSS was about Freedom. It was about exposing equality within source code. It allowed everyone equal rights and equal access to the technology they were using. An idea that if you were capable, you could fix code or pay someone to fix code. An ideology that there was something greater than yourself and that there was an inherent right built into what it is to be …

What is good for the community is good for the company (profit is the reward)

As the PostgreSQL community continues down its path of world domination I can't help but wonder whether the various PostgreSQL companies are going to survive the changes. Once upon a time there was an undercurrent of understanding that what was good for the community was good for the company. Whatever company that may be. However, over the last few years it seems that has changed. It seems there is more …

PgConf.US: 2016 Kicking the donkey of PostgreSQL Replication

My slides from my presentation and PgConf.US 2016:

 

Spreading the conference love

The PostgreSQL community has a lot of conferences in the United States:
  • PgUS United States PostgreSQL Conference 
  • Citus Data PgConfSV
  • PgUS SCALE PgDay (which as of 2016 is really a conference within a conference)
  • PostgresOpen
  • EDB PostgresVision
And that doesn't come even close to the number of various conferences in Europe.

As Bruce Momjian pointed out in his excellent blog this is a good thing. It is true that in …

You are my fellow community member

I attended the fantastically presented PgConf US 2016 last week. An amazing conference, my training was well attended, my talk was at capacity, the 20th Anniversary Party was phenomenal and the conference raised money for an excellent cause. There were over 435 attendees, giving our brothers and sisters at PgConf EU something to work for during their conference in November.

While attending the hallway track, I was talking to …

PostgreSQL, FOSS, SCALE, NYCPUG, SPI, LFNW and Ruby oh my!

Three weeks ago I was in Pasadena for SCALE 14. I had over 100 people in my room as I blistered the behind of PostgreSQL and how it handles backups. If you are interested in seeing my considered opinion I will also be training on the same topic at PgConf.US. I am also speaking on PostgreSQL Replication and finally, I was told that I am running the Lightning …
