Internally, the store now uses a shared key metadata table with kind, value, and expires_at columns, plus per-type child tables for hash fields, list items, set members, sorted-set members, stream entries/group state, and time-series samples. JSON documents, vectors, probabilistic structures, and time-series metadata are stored directly in the parent row payload, and streams persist their last-generated id in the parent row while entries, fields, groups, consumers, and pending metadata live in child tables. TTL is tracked on the parent key row and child rows are deleted through foreign-key cascades.

Probabilistic structures currently use exact persisted state to satisfy the upstream API without external PostgreSQL extensions: Bloom filters track exact membership, Cuckoo filters track exact per-item counts, HyperLogLog stores an exact distinct set, TDigest stores exact values, and TopK stores exact counts with deterministic top-k ordering.

Time series use parent-row JSON metadata for retention, duplicate policy, and labels, plus a sample child table keyed by timestamp. Range aggregation currently supports AVG, SUM, MIN, MAX, and COUNT, and multi-range filtering matches exact label pairs while omitting matching series that have no samples in the requested range.

Build and test

dotnet restore .\Dredis.Extensions.Storage.Postgres.slnx
dotnet build .\Dredis.Extensions.Storage.Postgres.slnx -c Release
dotnet test .\Dredis.Extensions.Storage.Postgres.slnx -c Release

The test project includes PostgreSQL integration coverage for the string, hash, list, set, sorted-set, JSON, stream, vector, probabilistic, and time-series slices. Set DREDIS_POSTGRES_TEST_CONNECTION_STRING to run those tests against a real PostgreSQL instance; otherwise the integration tests return early and the rest of the suite still runs.
