PostgreSQL Unlogged Tables - Look Ma, No WAL! | Crunchy Data Blog
While supporting customers at Crunchy Data, I sometimes see users add unlogged tables. In this post, I'm going to review some of the specifics about this. Unlogged tables in Postgresql are a way of preventing specific tables from generating WAL (Write Ahead Log) information by adding the unlogged keyword to a create table command: CREATE UNLOGGED TABLE foobar (id int); You can also change existing

The Part of PostgreSQL We Hate the Most
This article was written in collaboration with Bohan Zhang and originally appeared on the OtterTune website. There are a lot of choices in databases (897 as of April 2023). With so many systems, itâ€™s hard to know what to pick! But there is an interesting phenomenon where the Internet collectively decides on the default choice for new applications. In the 2000s, the conventional wisdom selected MyS

Deep PostgreSQL Thoughts: The Linux Assassin | Crunchy Data Blog
If you run Linux in production for any significant amount of time, you have likely run into the "Linux Assassin" that is, the OOM (out-of-memory) killer. When Linux detects that the system is using too much memory, it will identify processes for termination and, well, assassinate them. The OOM killer has a noble role in ensuring a system does not run out of memory, but this can lead to unintended

How do I install just the client tools for PostgreSQL on Windows?
I have a PostgreSQL database on a Linux system that I want to access from my Windows PC. But the only Windows binaries I have been able to find are the full installer, which includes the database server and client. Is it possible to get a client-only Windows binary install for PostgreSQL from anywhere? (To clarify, I want the standard PostgreSQL client, psql - not a GUI client or independent tool)
