Sometimes when we have an existing database and schema full of tables, there comes a time when we need to perform a migration. Maybe it’s because we want to move to or from a cloud service. Perhaps we have a small database and want to do a quick version upgrade via dump / restore. Whatever the reason, we may decide to clean up some technical debt while we’re making the transition. Many Postgres experts recommend against creating objects in the public schema. This is the default schema that exists in nearly all Postgres databases, and there are often implicit grants that could make our objects ..read more

Back on March 28, I asked the Postgres community whether new services for PGXN v2 should be written in Go, Rust, or “some of each”. I went so far as to create a poll, which ran through April 12. A month later you might reasonably be wondering what became of it. Has David been refusing to face reality and accept the results? The answer is “no”. Or at least I don’t think so. Who among us really knows ourselves. Since it closed, the poll has provided the results since it closed, but I suspect few have looked. So here they are: Candidate Votes % All Votes ? Rust 102 60.4% ?️ Go 53 31.4 ..read more

Last Tuesday (May 7, 2024) happened PGConf.BE in Leuven, Belgium. Living in Belgium myself, going to tech conferences in my own country is always a little bit special (and so much fun!). While it was only the 4th time that the event was (very successfully) organized, and despite the attendance was not very high, this cozy conference still manage to have great line-up of talks every year! (Previous years schedules for reference: 2019, 2022, 2023) As opening talk, Pavlo Golub (Cybertec) told us about how they came to create the pg_timetable job scheduler for PostgreSQL. Briefly said, using syst ..read more

Multi-master architecture has gained significant traction in the world of database management, offering a solution to traditional limitations in scalability, fault tolerance, and high availability. By allowing multiple nodes to operate as master, this architecture promises a more flexible and robust database system. However, along with these benefits come certain challenges, including data consistency, resource […] The post Understanding Multi-Master Architecture in PostgreSQL: Benefits and Trade-offs appeared first on Stormatics ..read more

I have just completed the first draft of the Postgres 17 release notes. It includes developer community feedback but still needs more XML markup and links. The release note feature count is 188. The most pleasant surprise for me was the large number of optimizer improvements. Postgres 17 Beta 1 should be released soon. The final Postgres 17 release is planned for September/October of this year ..read more

Whether you are managing a large table or setting up automatic archiving, time based partitioning in Postgres is incredibly powerful. pg_partman’s newest versions support a huge variety of custom time internals. Marco just published a post on using pg_partman with our new database product for doing analytics with Postgres, Crunchy Bridge for Analytics. So I thought this would be a great time to review the basic and complex options for the time based partitioning. Time partitioning intervals When I first started designing pg_partman for time-based partitioning, it only had preset intervals that ..read more

The PostgreSQL Global Development Group has announced minor version updates to all supported PostgreSQL versions : 16, 15, 14, 13, and 12. These minor version updates introduce over 55 bug fixes that have been reported in recent months, reflecting PostgreSQL’s commitment to stability and performance.

Tuning Parameters vs. Tuning Queries is yet another talk that “almost made it” to a couple of conferences but ended up being on the reserve list, and I never had to present it anywhere except for Chicago PUG. And one more time, my friends at Microsoft are giving me a chance:) I used to be skeptical about online conferences because I had a couple of disastrous experiences, but not with that team! This year, I am happy to do it again!. On June 11, my talk, Tuning Parameters in Postgres vs. Tuning Your Queries, will be streamed at POSETTE 2024. Tune in on June 11 at 8-30 AM CT ..read more

Mapping Oracle Number Data types using any conversion tools has always been a topic of conversation that I’ve engaged in with my customers and partners. Schema conversion and data type conversion are among the first tasks we undertake once migration is initiated post-assessment. I have previously collaborated and contributed a detailed article on number data type mapping and its significance. Feel free to give it a read. [1] , [2] and [3] In this blog, we’ll delve into how two of my favorite conversion tools, the AWS Schema Conversion Tool and Ora2pg, facilitate and support Number Data type ma ..read more
