Tembo Postgres monitoring needs pg_stat_statements or it silently does nothing

  • Related public instructions; check applicability and missing conditions.

Shows how to fix tembo Postgres monitoring needs pg_stat_statements or it silently does nothing. Use it when you hit this exact problem. Skip it when your error message or symptom looks different.

When it applies

Not specified by the original author.

Instructions

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.

Evidence

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.

postgres pg_stat_statements setup guide

  • Related public instructions; check applicability and missing conditions.

Shows how to set up pg_stat_statements for Postgres query monitoring. Use it when you need to find slow queries, when setting up a new database, or when query stats look empty. Not for real-time process inspection.

When it applies

Not specified by the original author.

Instructions

TL;DR

pgstatstatements needs sharedpreloadlibraries set and a server restart, then CREATE EXTENSION pgstatstatements in each database you want to monitor. It normalizes queries and tracks calls, total time, and mean time, which makes finding your worst queries a single query away. Reset stats with pgstatstatements_reset after deploys so old data does not skew the picture.

The query

postgres pg_stat_statements setup guide

Use this when

  • you need to find the slowest or most frequent queries in Postgres
  • you are setting up monitoring on a new database
  • pgstatstatements views are empty and you do not know why

Not for

  • seeing currently running queries, which is pgstatactivity
  • query monitoring in other databases, which have their own tools

Steps

  1. Add pgstatstatements to sharedpreloadlibraries and restart Postgres. The extension cannot load without the restart. Expected output: The server restarts and the library loads without errors.

  2. Run CREATE EXTENSION pgstatstatements in every database you want stats for. It is per-database, not global. Expected output: The pgstatstatements view returns rows in each target database.

  3. Find your worst queries: order by totalexectime desc for impact, or meanexectime desc for latency outliers. Expected output: You have a ranked list of queries by total and mean time.

  4. Reset stats after deploys or tuning changes so you measure the new reality, not history. Expected output: Post-deploy numbers reflect only post-deploy traffic.

  5. Set up a periodic snapshot of the view so you can compare week over week instead of relying on cumulative counters. Expected output: Historical snapshots exist for trend analysis.

Tembo Cloud ships pgmq, most managed Postgres providers ban it

  • Related public instructions; check applicability and missing conditions.

Shows how to fix tembo Cloud ships pgmq, most managed Postgres providers ban it. Use it when you hit this exact problem. Skip it when your error message or symptom looks different.

When it applies

Not specified by the original author.

Instructions

TL;DR

If your app needs pgmq, choose a provider that ships it, like Tembo Cloud or Supabase, or run your own Postgres. Never assume CREATE EXTENSION works on managed Postgres; check the provider's allowed-extensions list first, especially for newer compiled extensions.

Steps

  1. If your app needs pgmq, choose a provider that ships it, like Tembo Cloud or Supabase, or run your own Postgres.
  2. Never assume CREATE EXTENSION works on managed Postgres; check the provider's allowed-extensions list first, especially for newer compiled extensions.

Why this happens

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

Evidence

Source: Web self-hosting guide (Agora): documents the gotcha that most managed Postgres providers only allow extensions from a vetted allowlist and give no superuser access, so compiled C extensions like pgmq cannot be installed. Tembo Cloud is one of the providers that does ship pgmq. Agents writing migrations with CREATE EXTENSION pgmq will fail outright on RDS, Aurora, Cloud SQL, or Azure.

Verified resolution: If your app needs pgmq, choose a provider that ships it, like Tembo Cloud or Supabase, or run your own Postgres. Never assume CREATE EXTENSION works on managed Postgres; check the provider's allowed-extensions list first, especially for newer compiled extensions.
