synopsis: Type classes for PostgreSQL type mappings
description:
  Core type classes and algebra extracted from the postgresql-types library.

  Defines the fundamental abstractions for mapping Haskell types to PostgreSQL types,
  including binary and textual encoding/decoding, type metadata, and error handling.

  This package provides the type class algebra without concrete type implementations,
  making it suitable as a lightweight dependency for libraries that want to define
  their own PostgreSQL type mappings or work with the postgresql-types ecosystem.
