Last9 introduces a new Discover Databases page focused on Postgres observability, featuring an Overview tab with throughput, p95 latency, error rate, Query Performance Index, and top query breakdowns, plus a Connections tab covering active/max connections, WAL age, and connection-pool charts. Data is sourced from OpenTelemetry client spans and the PostgreSQL exporter with drill-down into traces. Additional improvements include MCP chunking support for large trace and log queries, filtered alert config responses to stay within MCP token limits, and cold storage IAM role session duration validation. Bug fixes address Cursor MCP auth redirect URI failures and a 400 error in the get_exceptions endpoint.
