What's kind of unique about the distributed functions feature in Citus that's described in the blog post is that you can scale stored procedures horizontally if procedure calls query co-located shards, but it doesn't restrict you from doing queries and transactions across all shards. Happy to answer any questions or debate the merits/evils of stored procedures.
