Building postgres server as a library. Some early success, but initdb and in-process restarts are much harder than expected

  Do you mind elaborating more about the use case? Postgres itself is heavily engineered around OS process boundaries for both correctness and resiliency.

    I'm not sure it'll be a serious project, but the main goal is to use it in CI or dev, where setting up postgres is kind of a pain. I got it to work already by setting up the global context in single-user mode (like postgres --single) and exposing bindings for SPI operations. Yesterday night I got extensions working, but as this project builds as a static archive, the extensions also have to be part of the build. Both plpgsql and pgvector worked fine. The bigger challenge is dealing with global state -- comparing the pre-start and post-shutdown state of the process memory, about 200 globals change state. Been slowly making progress to get restarts working
