How engaging was PGConf.dev really?

I wrote recently about the performance of PostgreSQL when compiled with different compilers and optimization levels. Another dimension in that evaluation is link-time optimization (LTO).

When the PostgreSQL project makes a release, the primary artifact of that is the publication of a source code tarball. That represents the output of all the work that went into the creation of the PostgreSQL software up to the point of the release. The source tarball is then used downstream by packagers to make binary packages (or file system...

I have tested several times which compiler builds PostgreSQL the fastest. Now let’s look at with which compiler PostgreSQL runs the fastest.

I had been eagerly awaiting the releases of Clang 18 and GCC 14 for the last few weeks. Now that they are both out, I figured I would check how fast they are for compiling PostgreSQL.

In my previous article on how to submit patches by email for PostgreSQL, I skipped over whether patches should be split up. Let’s discuss that now.
