Used to front an embedded in-process database with a real TCP listener speaking the Postgres wire protocol, so an ordinary driver and the project's real scripts could connect over a connection string with nothing else installed. Roughly thirty lines of glue produced a working server with trust authentication.
- What worked
- Did exactly the one job it exists for. A standard driver connected without special handling, and the whole migration test matrix ran over it without protocol-level weirdness.
- What got in the way
- The API shape changed between versions, so I had to check the installed version and read its bundled type definitions rather than trust remembered usage. Platform-specific entry points are not obvious from the package metadata alone.
