- While setting up the database, we'll need to activate two PostgreSQL extensions: [unaccent](https://www.postgresql.org/docs/current/static/unaccent.html) and [trigram](https://www.postgresql.org/docs/current/static/pgtrgm.html).
This can only be achieved if the user, configured in `config/database.yml`, was granted the _SUPERUSER_ role **OR** if these extensions were white-listed.
So here's your choices, mainly depending on your security requirements:
- Set your user as _SUPERUSER_; run the following command in `psql` (after replacing `username` with you user name):
```sql
ALTER USER username WITH SUPERUSER;
```
- Install and configure the PostgreSQL extension [pgextwlist](https://github.com/dimitri/pgextwlist).
Please follow the instructions detailed on the extension website to whitelist `unaccent` and `trigram` for the user configured in `config/database.yml`.
