PostgreSQL 19 hit Beta 4 with a release candidate expected in early October, including an automatic NOT IN to NOT EXISTS rewrite that unlocks better anti-join plans. A Neon branch test showed CI-passed migrations failing hard against real production data, including one that silently deleted over 2 million rows. Databricks keeps shopping, snapping up spreadsheet startup Row Zero as part of a larger acquisition spree. ## Content **TLDR:** Google Cloud pushed AlloyDB into agent territory with sandboxed, scale-to-zero Postgres instances that spin up in seconds. PostgreSQL 19 hit Beta 4 with a release candidate expected in early October, including an automatic NOT IN to NOT EXISTS rewrite that unlocks better anti-join plans. A Neon branch test showed CI-passed migrations failing hard against real production data, including one that silently deleted over 2 million rows. Databricks keeps shopping, snapping up spreadsheet startup Row Zero as part of a larger acquisition spree. --- ## AlloyDB adds sandboxed, scale-to-zero Postgres instances for AI agents Google Cloud's new preview lets AI agents spin up isolated AlloyDB instances in seconds with read-only access to production data that's current to the second. The instances run on Colossus storage for sub-millisecond I/O and claim throughput north of 3 million queries per second, then scale to zero and stop billing once the agent is done. You still get the full Postgres engine underneath, including vector, full-text, and spatial search, plus direct BigQuery/Spark integration without a separate ETL step.

A write-up walks through what happens when you rehearse Postgres migrations against a realistic 453MB production copy instead of a 200-row CI fixture: two migrations broke on real data (duplicate emails, NULL phones), two caused multi-second stalls from table locks, and one silently deleted over 2 million orders from a missing WHERE clause. The fix is a four-step rehearsal process on a Neon copy-on-write branch under live traffic, with CREATE INDEX CONCURRENTLY and expand-contract patterns as the actual remedies. There's also a ready-to-use GitHub Actions workflow that runs this on every pull request.

Some previously planned features got reverted to keep the release schedule predictable, with a promise to revisit them later. Separately, PostgreSQL 19 will automatically rewrite NOT IN into NOT EXISTS whenever NOT NULL constraints guarantee equivalence, finally letting the planner use all anti-join strategies instead of the weaker plans NOT IN usually forces.

Terms weren't disclosed, though Row Zero had previously raised $10 million at a $40 million valuation. CEO Ali Ghodsi confirmed more deals are coming after a 2026 spree that already included Quotient AI, SiftD.ai, Panther, and Electric, backed by a $5 billion raise at a $190 billion valuation.

[Read more](https://daily.dev/posts/oKvoAE6Sb) - **Gartner projects 150,000 AI agents per Fortune 500 company by 2028:** That's up from fewer than 15 in 2025, with only 13% of organizations feeling prepared to govern them, which is the number behind Yugabyte's pitch for agentic multitenant Postgres with MCP-exposed lifecycle operations. [Read more](https://daily.dev/posts/ENSdOiVnE) - **Doltgres adds multi-dimensional arrays matching Postgres semantics:** The version-controlled Postgres-compatible database now supports array literal syntax, subscript updates, and functions like array_position and unnest behaving identically to real Postgres.
