Stream-mode WAL batching means post-snapshot catch-up stops stalling on bulk-INSERT and DELETE tables (Postgres sink only for now; UPDATE still goes one at a time). Decode-time table filtering inside Postgres via wal2json. https://github.com/xataio/pgstream/releases/tag/v1.0.213 May 2026 16:20 +0000at://did:plc:2stusqj3jmuggubunclyh6bz/app.bsky.feed.post/3mlqphyk3ms2shttps://bsky.app/profile/xata.io/post/3mlbcsw5ors2wEvery Xata Postgres branch now has a managed PgBouncer endpoint, in the same memory envelope as the database. Auto-tuned to 0.9 of max_connections. 10,000 client connections per branch. Hibernates with the branch. Append `-pooler` to your branch ID.

Schema changes are now emitted directly into WAL as logical messages, without schema logs or stored schema state. If you work with Postgres CDC, this might be interesting.

A domain is a custom data type with rules attached, and Postgres stores those CHECK constraints right in `pg_constraint` linked by `contypid` instead of `conrelid`.

Types tell you *what* can be stored but constraints enforce *what must be true*. If a row violates a rule, Postgres rejects it. No silent corruption.
