Developing PostgreSQL for Windows, Part 1

January 29, 2020/3 Comments/in Eisentraut's PlanetPostgreSQL, PostgreSQL /by Peter Eisentraut

As a PostgreSQL developer, I occasionally need to make my code work on Windows. As I don’t normally use Windows and don’t have a permanent Windows installation around, this has always been a bit cumbersome. I have developed a few techniques to make this easier, and I figure they are worth sharing. And actually this […]

Preamble How many current Barman users have thought about saving backups in a remote destination in the cloud?

PostgreSQL 12: Implementing K-Nearest Neighbor Space Partitioned Generalized Search Tree Indexes

November 5, 2019/3 Comments/in 2ndQuadrant, Kirk’s PlanetPostgreSQL, PostgreSQL /by Kirk Roybal

K-nearest neighbor answers the question of “What is the closest match?”. PostgreSQL 12 can answer this question, and use indexes while doing it.

Managing another PostgreSQL Commitfest

October 15, 2019/1 Comment/in 2ndQuadrant, Alvaro's PlanetPostgreSQL, PostgreSQL /by Álvaro Herrera

I have written about managing a PostgreSQL commitfest before. During the PostgreSQL 13 development cycle, I did it again. This time I used a different strategy, mostly because I felt that there was excessive accumulation of very old patches that had received insufficient attention. So apart from bugfixes (which are always special cases), I focused […]

PostgreSQL 12: Foreign Keys and Partitioned Tables

October 14, 2019/7 Comments/in 2ndQuadrant, Alvaro's PlanetPostgreSQL, PostgreSQL /by Álvaro Herrera

Now that PostgreSQL 12 is out, we consider foreign keys to be fully compatible with partitioned tables. You can have a partitioned table on either side of a foreign key constraint, and everything will work correctly. Why do I point this out? Two reasons: first, when partitioned tables were first introduced in PostgreSQL 10, they […]

Postgres is the coolest database – Reason #2: The License

April 24, 2019/0 Comments/in PostgreSQL, Umair's PlanetPostgreSQL /by Umair Shahid

Legal documents = SCARY!! That’s the typical equation, and it’s true – except when it comes to PostgreSQL. Let me explain… I have been told by both prospects and clients, that when they sit down to negotiate terms with Oracle, they are faced with more lawyers than they have engineers. No wonder one shudders at […]

Postgres is the coolest database – Reason #1: Developers love it!

April 8, 2019/3 Comments/in PostgreSQL, Umair's PlanetPostgreSQL /by Umair Shahid

PostgreSQL has been my livelihood since 2004 – so I am naturally biased in its favor. I think it is the coolest piece of software on the planet, and I am not alone. DB-Engines See those 2 badges up there? That’s 2 years in a row. DB-Engines monitors a total of 343 databases and their […]

Having Group By Clauses — elein’s GeneralBits

March 18, 2019/0 Comments/in Elein’s PlanetPostgreSQL, PostgreSQL /by Elein

Some people go to great lengths to avoid GROUP BY and HAVING clauses in their queries. The error messages are fussy but they are usually right. GROUP BY and HAVING key words are essential for good SQL reporting. The primary reason for GROUP BY is to reduce the number of rows, usually by aggregation. It […]
