Super interesting project! I have zero experience writing Postgres extensions, but I was browsing a blog post about an extension the other day. I was curious what ones workflow looked like while developing a PG extension. From the little I read, it looked like you would have to recompile postgres, including your extension, then enable it just to run it. Seems like a very long feedback loop. Was I missing something?

Glad you like it!

You don't need to recompile it actually! It's enough to compile your extension and Postgres can then dynamically link to it, which makes for a perfectly good feedback loop. pgfdb is built with pgrx: https://github.com/pgcentralfoundation/pgrx, which is a framework for building Postgres extensions in Rust that handles all the compiling and linking for you. Highly recommend that if you want to try writing extensions and are also a fan of Rust!
