PgDog, a Postgres scaling proxy, secures $5.5M in funding
PgDog, a three-person startup, announced it has raised $5.5M in funding to scale its Postgres horizontal scaling proxy product. The tool aims to make Postgres handle massive workloads (100TB+ tables, 1M+ queries per second) without requiring alternative databases like MongoDB or DynamoDB. The company claims over 1.4M Docker pulls and is currently serving 2M+ queries per second across production deployments.
PgDog is a proxy layer designed to make PostgreSQL horizontally scalable, addressing what the founders identify as Postgres's primary limitation that has driven adoption of alternative databases. The startup, founded by infrastructure engineers with prior experience scaling Postgres at companies like Instacart, has already deployed the open-source tool across dozens of production systems handling over 2M queries per second and sharding more than 20TB of data. With $5.5M in funding from investors including Basis Set, Y Combinator, and Pioneer Fund, the team plans to develop an enterprise edition with AWS integration and SLA-backed support. The product is available as open source with weekly releases and operates without vendor lock-in, deployable on-premises, in cloud accounts, or locally.
What's missing
The announcement does not provide independent verification of the claimed metrics (2M queries per second, 1.4M Docker pulls, 20TB sharded), nor does it discuss potential limitations of the proxy approach, competitive alternatives in the Postgres scaling space, or technical details about how sharding is implemented.

Anthropic CEO Calls for FAA-Style Regulation of Powerful AI Models
Anthropic CEO Dario Amodei published an essay calling for government regulation of powerful AI models, comparing the approach to FAA oversight of commercial aviation. The proposal includes mandatory third-party testing for frontier models and potential government authority to block or delay their deployment if they pose safety risks. The call comes as Anthropic released Claude Fable 5 and an updated Claude Mythos 5 model with advanced cybersecurity capabilities.
