Neues vom PostgreSQL Planet

In #PostgresMarathon 2-008, we discovered that prepared statements can dramatically reduce LWLock:LockManager contention by switching from planner locks (which lock everything) to executor locks (which lock only what's actually used). Starting with execution 7, we saw locks drop from 6 (table + 5 indexes) to just 1 (table only).

There we tested only a simple, unpartitioned table. What happens if the table is partitioned?

For this second entry into our blog feature to celebrate 25 years of CYBERTEC, our CEO gave some interesting insights into what he expects of the future - for the company as well as PostgreSQL as a whole.

CYBERTEC in another 25 years

Interviewer: Let's talk about the future. Where do you think you see CYBERTEC in another 25 years? 

Postgres database-level “synchronous replication” does not actually mean the replication is synchronous. It’s a bit of a lie really. The replication is actually – always – asynchronous. What it actually means is “when the client issues a COMMIT then pause until we know the transaction is replicated.” In fact the primary writer database doesn’t need to wait for the replicas to catch up UNTIL the client issues a COMMIT …and even then it’s only a single individual connection which waits. This has many interesting properties.

PostgreSQL logical replication adoption is becoming more popular as significant advances continue to expand its range of capabilities.  While quite a few blogs have described features, there seems to be a lack of simple and straightforward advice on restoring stalled replication. This blog demonstrates an extremely powerful approach to resolving replication problems using the Log […]

I volunteered as a room host and Slonik guide.
Best gig: posing our elephant. The photographer had runway-level ideas. Slonik delivered every single time.

QGIS and PostgreSQL working well together

Creating an extension for Postgres is an experience worthy of immense satisfaction. You get to contribute to the extension ecosystem while providing valuable functionality to other Postgres users. It’s also an incredibly challenging exercise in many ways, so we’re glad you’ve returned to learn a bit more about building Postgres extensions.In the previous article in this series, we discussed creating an extension to block DDL.

In October 2025, PostgreSQL Conference Europe brought the community together in Riga, Latvia from the 21st to the 24th.
