Vibe Hacking Postgres
Rebase GiST amcheck and design useful corruption tests.
session summary
The group revived the long-running amcheck work for GiST indexes after shared infrastructure and the GIN checker had been committed. They manually rebased the remaining GiST patch, repaired build files and SQL upgrade scripts, and got its basic checks passing. They then asked Cursor to adapt newly committed GIN corruption tests. The generated tests initially assumed ordering that GiST does not have and later passed without actually corrupting indexes, leaving only a useful page-header corruption idea and more manual work.
