Vector health

The Vector Health tab monitors pgvector indexes and embedding storage on the connected instance. It is always visible in the sidebar but shows a "not installed" card when pgvector is not present.

What it checks​

  • Index type distribution — HNSW vs IVFFlat index usage
  • Unused vector indexes — indexes with zero scans that consume disk space
  • Unindexed embedding tables — tables with vector columns that lack an index
  • Index configuration — distance metrics, index build parameters

Requirements​

pgvector must be installed (CREATE EXTENSION IF NOT EXISTS vector). Without it, the tab shows a prompt with the installation command.

Connection to Index Advisor​

Vector index bloat and usage patterns feed into the broader index analysis workflow alongside B-tree, GIN, and BRIN diagnostics.
