A story about how I dug into the PostgreSQL sources to write my own WAL receiver

You really get a sense for how much the author learned from this experience. And I like how he developed a respect for C.

Given all the corner cases he describes, it seems like a good example of something you would never ever want to vibe code.

nice work

I wonder if you considered WAL-G, which is also written in Go

and has this: https://github.com/wal-g/wal-g/blob/master/docs/PostgreSQL.m...
