An experiment to create postgres extensions using Rust pgrx infrastructure.
Also, it's another project to explore brazilian document numbers (CNPJ, CPF, PIS, RG) by creating strong types to each one. The postgres type system will grant:
- check digits validation
- int64 storage (better performance and indexing)
- string conversion and mask
cargo pgrx package # pg_config must be on PATH
psql
CREATE EXTENSION pgbrtypes;
SELECT CNPJ '191';
cnpj
