      We at Fujitsu have been actively contributing to the PostgreSQL opensource community since 2003, participating in the development of new features, bug fixes, and code review. Today I would like to talk about what a typical day is like as a Postgres engineer.


      I have the privilege of opening this series of articles detailing what a typical day as a Postgres engineer at Fujitsu entails.

      My primary responsibility within the team is reviewing my colleague's patches.

      About me

      I began working for Fujitsu in the early 1990s, based in Sydney Australia. I have been involved in many and varied projects since then, some of which required trips to Japan to work closely with the relevant teams. Highlights include a C port of RDB2 database to Windows NT, working with the first versions of Java, contributing to some ODBC/JDBC adaptors, and making a JMS implementation. For several years I was a core member of the Interstage development team (Fujitsu’s J2EE Enterprise Java Beans container product) focusing on the CMP and MDB modules. Other development projects included some web-based (JavaScript) UI applications, and an Augmented Reality PoC.

      I was seconded to customer sites for a couple of years, and for a while I became the local expert for a Fujitsu call-centre Chat-Bot (CHORDSHIP). Eventually fate moved me to the Fujitsu Enterprise Postgres development team where I worked mainly on transparent encryption components.

      My involvement with Fujitsu Enterprise Postgres led to an opportunity to join the Fujitsu OSS PostgreSQL team, which I have been a member of since 2019. Within this team, my main task currently is the reviewing my colleague’s patches – an activity which makes me a regular poster to the pgsql-hackers mailing list. Last year, I received recognition as a PostgreSQL Contributor. I have also written some PostgreSQL blogs and have co-presented a session at the PGCon 2023 conference in Ottawa.

      A typical day at Fujitsu OSS team

      Since the COVID pandemic, I’ve been working remotely from home. I usually try to start work early about 7.30am. Due to my location on the East coast of Australia, I am generally the first person of our international OSS team to see the overnight activity from Europe and the US. So, my day begins by going through all new pgsql-hackers and pgsql-bugs posts to identify those related to Logical Replication. If any, then I will notify my colleagues via internal mail or MSTeams.

      My primary responsibility within the team is reviewing my colleague’s patches, so next, I check for new patch versions. I use Windows BeyondCompare tool for comparing patch versions, and the CentOS meld tool for source code comparisons (after applying the patch). To keep track of my review comments, I maintain color-coded tables in MSWord (don't ask why, it just works well for me).

      I aim to post my reviews by lunchtime so that they are available when my colleagues in India begin their workday. In the afternoon I continue with review tasks, to post more, or to get a head start on what I plan to post the next day.

      My day typically finishes around 6PM. Ideally, while I am sleeping, my review comments will get addressed and a new patch version will be posted, so the next day the cycle repeats.

      My favourite part of the experience

      Code reviewing patches may seem mundane, but I don’t find it that way because the task suits my character. I have been using C programming language since the 1980s so it is extremely familiar to me, and I especially enjoy finding and suggesting succinct ways to achieve the same functionality in less code. It is not too dissimilar from my hobby of C code-golfing on the CodeWars programming site - you can read more about that in the PostgreSQL Person Of the Week interview I gave some time ago.

      I easily recognize patterns that seem to go unnoticed by others – e.g., I am that guy who will find the single typo in a 300-page novel and become distracted by it. In daily life this can be an annoying trait, but it proves useful for tasks like code reviewing and helping with patch quality-control. In another life I might have been a copy editor.

      Wrapping up

      This year, I hope to continue posting valuable review comments to help maintain high-quality patch code in PostgreSQL.

      But I also want to try making a habit of taking my own notes on whatever code logic I am reviewing, because doing so will make it easier to write technical blogs about the feature at a later stage.
