0.1.0.0 - 2026-04-25

Initial release. Pure-Haskell implementation of the PostgreSQL v3 wire protocol.

  • Connection setup over TCP and Unix sockets, TLS 1.2/1.3, cleartext / MD5 / SCRAM-SHA-256 authentication, multi-host failover (target_session_attrs, load_balance_hosts), startup parameters.
  • Connection pool with idle reaping, health checks, jittered max-life, queue mode (LIFO/FIFO), recycling modes (always/on-error), lifecycle hooks, and nothunks-checked invariants.
  • Wire frames: extended query (parse / bind / describe / execute), simple query, COPY in/out, large objects, LISTEN/NOTIFY, query cancellation.
  • Binary format type classes (PgEncode, PgDecode) and OID metadata. Concrete codecs for PostgreSQL types live in the valiant runtime.
  • Nine structured error types with column-by-column diagnostics.
