Hacking the Postgres Wire Protocol
> One of the things that puts metaprogramming on wheels is being able to pull in grammars, schemas and such for external systems.
That's what I've been trying to do with: https://github.com/schemamap/schemamap
For a well-constrained Postgres schema, a deterministic SQL compiler can be built (with plenty of logic programming/constraint-solving/hypergraph-analysis) that can integrate arbitrary external systems data.
While this is NP-hard, with some clever use of embeddings and ontologies, and use of every single constraint AST within the DB to reduce the search space, this becomes feasible problem.
For any Clojurists interested, I've packaged `pg_query`, so you can use it in your applications: https://github.com/schemamap/pg-query-clj
At the moment I'm saving up for the next development cycle, so not only PG->PG schema mappings can be solved for (JSON schema is next!). Hope this sounds interesting :)
