Tembo Postgres monitoring needs pg_stat_statements or it silently does nothing

TL;DR

Run CREATE EXTENSION IF NOT EXISTS pgstatstatements on any database you connect to Tembo's Postgres integration. Without the extension installed, slow query detection and missing-index suggestions silently do nothing.

Steps

1. Run CREATE EXTENSION IF NOT EXISTS pgstatstatements on any database you connect to Tembo's Postgres integration. If slow queries are not being flagged, check the extension exists before debugging the integration itself.

When to use

You are seeing this: If slow queries are not being flagged, check the extension exists before debugging the integration itself. Use this skill when you run into "Tembo Postgres monitoring needs pgstatstatements or it silently does nothing".

When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.

Source: Official docs (Postgres integration): documents the gotcha that Tembo's Postgres integration monitors your database using pgstatstatements. Without the extension installed, slow query detection and missing-index suggestions silently do nothing. Agents that connect Tembo and expect monitoring must run the extension DDL first.

Verified resolution: Run CREATE EXTENSION IF NOT EXISTS pgstatstatements on any database you connect to Tembo's Postgres integration. If slow queries are not being flagged, check the extension exists before debugging the integration itself.
