Update pgwire-replication requirement from 0.2 to 0.3

[dependabot]

Updates the requirements on pgwire-replication to permit the latest version.

Changelog

Sourced from pgwire-replication's changelog.

[0.3.1] - 2026-03-28

Improved

• Drain-phase tight loop in stream_loop: while the BufReader has buffered data, reads up to 256 messages without select!/timeout overhead, then falls back to the wait path only when the buffer is empty
  • Eliminates per-message tokio timer registration/deregistration during burst reads
• Reusable read buffer via read_backend_message_into(): reuses a BytesMut across messages instead of allocating a new Vec per WAL message
  • Reduces allocator pressure during high-throughput streaming

Benchmarked

• Postgres CDC backlog drain: 37K -> 48K events/s (+32%) in DeltaForge on Docker (direct connection, batch=4000, kafka linger.ms=0)

[0.3.0] - 2026-03-27

Changed

• Breaking: PgWireError::Io now wraps Arc<std::io::Error> instead of String
  • Consumers can match on .kind() (e.g. ErrorKind::UnexpectedEof, ConnectionReset) instead of brittle substring matching on error messages
  • PgWireError remains Clone via the Arc wrapper

Improved

• Wrapped the replication stream in a 128KB BufReader, batching WAL messages into fewer recv() syscalls
  • Reduces syscall overhead significantly during backlog drain scenarios

Removed

• Replaced rustls-pemfile dependency with rustls-pki-types PEM parsing (already in the dependency tree via rustls)
  • Resolves RUSTSEC-2025-0134 (unmaintained crate)

---

[0.2.0] - 2026-02-08

Added

• Support for pg_logical_emit_message() via new ReplicationEvent::Message variant
  • Messages are always enabled (messages 'true' in pgoutput protocol options); zero overhead when unused
  • Both transactional and non-transactional messages are supported
  • Events include prefix (application-defined string), content (raw bytes), lsn, and transactional flag
• Unix domain socket connections: set host to a socket directory path (e.g. /var/run/postgresql)
  • Follows libpq convention: any host starting with / is treated as a socket directory
  • Socket path is {host}/.s.PGSQL.{port}
  • ReplicationConfig::unix() convenience constructor
  • ReplicationConfig::is_unix_socket() and ReplicationConfig::unix_socket_path() helpers

Changed

• START_REPLICATION now includes messages 'true' in pgoutput options (previously only proto_version and publication_names)

[0.1.2] - 2025-01-17

Fixed
