'Rusting' a New Postgres C Extension to Count Subtransactions — A subtransaction, or nested transaction, is a transaction that begins within another transaction, and while useful, performance implications exist. pg_subxact_counters is a new extension written in both C and Rust to count such subtransactions, and it's also useful as a way to compare the implementation of extensions in both languages.
