WhatAn agent that automatically detects the running kernel version and applies optimal sysctl and boot parameters for PostgreSQL, including hugepages, preemption settings, and NUMA configuration.
SignalCommenters note that fixes like enabling hugepages or disabling preemption are well-known but almost nobody actually applies them — the gap between knowing the right kernel settings and actually deploying them in production is enormous, and each kernel version adds new knobs.
Why NowThe Linux 7.0 preemption change means PostgreSQL admins now must actively tune kernel parameters that previously had safe defaults, turning optional optimization into a mandatory operational step.
MarketCompanies self-hosting PostgreSQL — estimated 500K+ production deployments. Competes with generic config management but nothing purpose-built for database-kernel co-optimization. Could charge $50-200/mo per server, $100M+ TAM.
MoatA continuously updated matrix of kernel-version-specific optimizations validated across real workloads creates switching costs and trust that generic tools can't match.
