Current Highlights (v0.26.3)

  • PostgreSQL startup now requests protocol 3.2 by default, with one-shot downgrade retry to 3.0 on explicit protocol-version rejection.
  • Native startup decode/handling for backend NegotiateProtocolVersion ('v') is now implemented.
  • Cancel key handling is bytes-native (4..=256), with public bytes-based cancel APIs for protocol 3.2 correctness.
  • Legacy i32 cancel access/cancel APIs are retained as compatibility wrappers for 4-byte key behavior.
  • Hardening/integration tests now cover protocol negotiation, downgrade boundaries, and startup/copy/replication harnesses under the 3.2 default.
