Avinash Vallarapu: Setting up Streaming Replication in PostgreSQL 13 and Streaming Replication Internals
While migrating to PostgreSQL, some of the users may be curious about the type of replication offered by PostgreSQL. Some might want to know if they have to pay any additional enterprise license in order to achieve this requirement. This is because, a few commercial databases require a customer to take an enteprise license to setup replication. But, PostgreSQL, like advanced Open Source databases, automatically offers several types of replication methods built-in.
Logging is an important topic and particularly useful for troubleshooting, debugging and monitoring. Many applications have their own build-in logging mechanism. Pgpool-II logging mechanism is similar to PostgreSQL logging mechanism. Pgpool-II log management system supports two ways for logging messages (stderr and syslog) and the logging collector process collects the logs sent to stderr and redirects them into log files. However, how can we manage the logging system on Kubernetes? In this blog, I will describe how to manage Pgpool-II container logs on Kubernetes.

Takayuki Tsunakawa: Faster Bulk Insertion to Foreign Tables - Introduction to PostgreSQL 14 Committed Features
Currently, the global PostgreSQL development team, led by Amit Kapila, continues to contribute to the community as part of Fujitsu's work on PostgreSQL. As a member of this team, I am actively working with talented and passionate community members around the world to advance PostgreSQL.
Our team will publish blog posts focusing on the features and patches that members have worked on. This article discusses "Batch Insert to Foreign Table" committed to PostgreSQL 14, explaining why we've worked on it and the resulting exciting performance improvements.
One of the performance projects I’ve focused on in PostgreSQL 14 is speeding up PostgreSQL recovery and vacuum. In the PostgreSQL team at Microsoft, I spend most of my time working with other members of the community on the PostgreSQL open source project.
An interesting extension that helps removing bloating from tables and databases.
A simple view to see if a user can perform backups.
Just like any advanced relational database, PostgreSQL uses a cost-based query optimizer that tries to turn your SQL queries into something efficient that executes in as little time as possible. For many people, the workings of the optimizer itself remain a mystery, so we have decided to give users some insight into what is really going on behind the scenes.
