//! # guardian-relational
//!
//! The relational foundation for GuardianDB's PostgreSQL compatibility layer.
//!
//! This crate is deliberately free of any dependency on GuardianDB's networking /
//! iroh stack so that the relational core compiles and tests quickly and can be
//! reused by embedders. It provides:
//!
//! * [`SqlType`] — the PostgreSQL-compatible type system with OIDs.
//! * [`SqlValue`] — the runtime value model with canonical JSON encoding, wire
//!   text I/O, three-valued comparison and casts.
//! * [`Catalog`] — schemas, tables, columns, constraints, indexes, sequences and
//!   views, fully serializable for persistence and transaction snapshots.
//! * [`RelationalStorage`] — the document-collection persistence boundary, with an
//!   in-memory implementation ([`MemoryStorage`]).
//! * Secondary index structures with composite keys and uniqueness enforcement.
//! * [`RelError`] — error types carrying PostgreSQL SQLSTATE codes.
