Commentary: PostgreSQL is well-liked for a wide range of reasons, but what has the PostgreSQL group completed to assure this lengthy march to attractiveness?
PostgreSQL went many years without having getting much in the way of accolades, just steadily releasing predictable, steady code. These days, its attractiveness has boomed, prompting me to generate regularly about its achievement: Amazon just open sourced an easier path to PostgreSQL, Developers more and more pair MongoDB with PostgreSQL, survey finds, and Why Oracle’s missteps have led to PostgreSQL’s ‘moment’ in the databases sector. I assumed I was completed, and then Technique Initiative cofounder Adam Jacob began riffing on the good reasons at the rear of PostgreSQL’s accomplishment, producing me to speculate what tends to make the group at the rear of PostgreSQL’s increase so distinct.
After all, as Jacob pointed out, “Other databases supply far better types for a given niche, but absolutely nothing so elegantly can be twisted into what ever condition you need it to be.” That might be true, but why is it correct? Arguably most databases try to be malleable to a wide array of use conditions. Even points like time sequence databases that the moment appeared specialized niche have absent typical purpose. So what did the PostgreSQL local community get right to permit it to not just aspire to in shape a broad assortment of use conditions, but in fact deliver?

Improved by style and design
You can find a ton to enjoy about PostgreSQL, together with its versatility. Soon after a long time of currently being set to do the job, it truly is perhaps not surprising that PostgreSQL can be quickly tailored, as Jacob referred to as out: “If you want, you can very easily make the database feel fully custom to your domain product–the application can be absolutely summary from the underlying implementation. Of class, if you will not like that, you can truly feel absolutely free to just build migrations of the basic schema, and put that SQL straight in your software. Both equally paths function, both equally are optimized and understood.”
Once again, all good, but PostgreSQL is not exclusive in striving for this objective. Rather, it’s somewhat distinctive in basically accomplishing it.
For this, a wonderful offer of credit score goes to the man or woman who to start with created the database: Michael Stonebreaker. As Berkeley computer system science professor Joseph Hellerstein wrote about Stonebreaker’s legacy:
Although several factors have changed in 25 a long time, the standard architecture of PostgreSQL continues to be fairly similar to the college releases of Postgres in the early 1990s, and builders common with the present-day PostgreSQL source code would have minimal problems wandering via the Postgres3.1 supply code (c. 1991). All the things from source code listing constructions to process structures to knowledge structures continue to be remarkably identical. The code from the Berkeley Postgres workforce experienced fantastic bones.
Crunchydata’s Craig Kerstiens builds on this, arguing that “[A]s a database it took a counterintuitive approach to most. It was never ever the ‘easy to use’ database, [to be honest] it however isn’t really when as opposed to some other folks. But it focused on correctness. It has considering that develop into [easier] to use, but that commitment for 20 decades on correctness matters.” This plan is echoed by Datasette founder Simon Willison: “I actually value how high the bar is for introduced features. When a new function results in being accessible in PostgreSQL I know I can have confidence in it straight absent, since I know how superior their criteria are.”
Nevertheless the “bones” had been at first sound, it has been this commitment to correctness and high-quality more than a very long period of time that genuinely marks PostgreSQL. Other open resource database communities, which include MySQL, argued the CockroachDB people, have not finished really as properly as PostgreSQL in this regard (“MySQL experienced developed organically more than time in a rather significantly less principled method than PostgreSQL”).
PostgreSQL normally isn’t really the initially with slicing-edge features–that’s not genuinely its purpose. Somewhat, the PostgreSQL community has, around time, achieved a thing extraordinary exactly by not aspiring to any outstanding, field-changing functionality: Boredom. Or, fairly, as Google’s Kelsey Hightower adroitly expressed it, “Postgres is what comes about when tech gets so great, for so extended, it becomes boring.”
