That fits with my experience. I used Claude Code to put together a pretty complex CRUD app and it worked quite well. I prompted it to write the code for the analysis worker, and it produced some quite awful code with subtle race conditions which would periodically crash the worker and hang the job.
On the plus side, I got to see first-hand how Postgres handles deadlocks and read up on how to avoid them.
