Replaced the per-connection prepared-statement cache with SIEVE (NSDI'24). In standalone microbenchmarks, SIEVE is 2.3-3.8x faster than the previous HashPSQ-based LRU across fill, hit-only, mixed, eviction-storm, uniform-random, and Zipf-skewed workloads.
Connection record fields changed: connStmtCache is now SieveCache ByteString ByteString (was IORef (HashPSQ ByteString Word64 ByteString)), and connStmtTick was removed (SIEVE doesn't need a monotonic tick).

PgWire.Cache.Sieve.clear, capacity, and foldEntries for managing and inspecting the per-connection cache.

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.
