Packaging PostgreSQL extensions is hard. Not because package formats are mysterious — but because the matrix is large. We are talking about 5 active PG major versions times 16 Linux platforms — that's 80 build slots per extension. Only a handful of extensions actually cover all of it. The PGDG YUM and APT repositories, maintained by Christoph and Devrim, already do foundational work. They carry many of the most important extensions — around 150 packages in total. But there are still gaps. Rust extensions, for example. And some OS-PG slots that aren't filled. So the complementary repo aims to fill that gap. It adds packages where PGDG coverage is missing, or where the build is too expensive to maintain — about 300 additional extension packages in total.
