I would like to request support for the unaccent extension on Railway's managed PostgreSQL instances.

What is unaccent?

unaccent is a text search dictionary shipped as part of the official PostgreSQL contrib package postgresql-contrib). It removes diacritical marks from strings, enabling accent-insensitive searches (e.g. matching "tetra" against "Tétra").

Why is it needed?

Without unaccent, it is not possible to implement reliable accent-insensitive full-text search purely in SQL on Railway PostgreSQL. The workaround — normalizing data in application code and storing redundant search columns — adds significant complexity and maintenance burden to the data model.

unaccent is a standard, widely-used, read-only extension with no security implications. It is already supported by other managed PostgreSQL providers such as Supabase, Render, and AWS RDS.

Expected behavior:

The following should execute without error on a Railway PostgreSQL instance:

```sql

CREATE EXTENSION IF NOT EXISTS unaccent;

SELECT unaccent('Héllo Wörld'); -- returns 'Hello World'

```

Request:

Please include unaccent in the list of supported extensions and ensure the pg_catalog.unaccent dictionary is available, either by enabling it by default or by allowing users to activate it via CREATE EXTENSION.

Regards.
