Upstream PostgreSQL remains the parser, planner, executor, catalogs, MVCC engine, and wire protocol.
Work in progress · engineering preview
PostgreSQL,
unbundled.
The PostgreSQL you already know, with quorum-durable WAL and immutable page history designed for object storage. Built in Rust. Coordinated at the edge. Made to recover, branch, and scale without copying a whole database.
Commits cross a fenced WAL quorum before acknowledgement. Object storage is the durable history, not a latency gamble.
Checksummed page layers and manifests are content-addressed. Branches reuse history instead of duplicating it.
One database.
Four clean layers.
DBlicious separates the parts PostgreSQL does brilliantly from the durability and lifecycle machinery needed by a cloud database.
PostgreSQL compute
Native clients, SQL semantics, extensions, MVCC, and query execution.
WAL quorum
Signed leader leases, epoch fencing, batching, fsync, and majority durability.
Page service
LSN-versioned relation pages, sparse writable overlays, and bounded reconstruction.
R2 history
Immutable layers, atomic manifests, instant branches, compaction, and retention.
Built in public.
Measured honestly.
This is an active engineering preview, not a production database offer. The site goes live early; customer provisioning waits for recovery, compatibility, and performance evidence.

No magic. No compatibility theater.
PostgreSQL 18 now replays DBlicious-reconstructed WAL to a selected LSN in the recovery drill. Database testing opens after automated promotion, upstream compatibility suites, and measured failure behavior match the promises on this page.
