0.1.0.1 - 2026-04-29

Changed

• Switched the per-connection prepared-statement cache used by Valiant.Execute and Valiant.Batch from a HashPSQ-based LRU to SIEVE (NSDI'24). In standalone microbenchmarks, SIEVE is 2.3-3.8x faster than the previous LRU across fill, hit-only, mixed, eviction-storm, uniform-random, and Zipf-skewed workloads. No public API change.
• Updated pg-wire lower bound to ==0.2.* (required to pick up the SIEVE-backed Connection and the PgWire.Cache.Sieve exports).

Removed

• psqueues dependency.

0.1.0.0 - 2026-04-25

Initial release. Runtime library on top of pg-wire. Re-exports the connection and pool APIs and adds:

• Binary codecs for the common PostgreSQL types: numerics, text, time, UUID, JSON / JSONB, hstore, inet, macaddr, point, ranges, arrays, composites, enums.
• A typed Statement p r value, query execution (fetchOne/fetchAll/fetchScalar/fetchExists/...), command execution (execute/executeReturning/executeBatch), pipelined batch execution.
• Server-side cursor streaming (withCursor, fetchBatch, fetchAllCursor).
• COPY in/out (binary and CSV), large objects, LISTEN/NOTIFY, advisory locks, transactions with isolation levels.
• refine and refineWith combinators in Valiant.Binary.Decode for validating decoded values against extra invariants without a full PgDecode instance.
• fetchAllUnboxed: an unboxed-vector variant of fetchAllVec for fixed-size primitive result columns. Eliminates per-element pointer indirection for Int32 / Int64 / Double / Bool and tuples of those.
