## TL;DR

Check SELECT * FROM pg_extension for pg_search before assuming the tokenizer is broken.

## Steps

1. If Nhost's Postgres says type icu does not exist when using pg_search tokenizers, two things must both be true: the database must be on a recent image (17.9 or later, where the maintainer fixed the packaging) and pg_search must actually be installed with CREATE EXTENSION in that database. Check SELECT * FROM pg_extension for pg_search before assuming the tokenizer is broken. The same applies to other extensions Nhost ships but does not enable by default.

## When to use

Use this skill when you run into "Nhost pg_search icu tokenizer missing: install the extension first".

## 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.
