# Create

Connect as a superuser on the host running
[PostgreSQL](https://docs.cyverse.org/deployment/01-foundation/postgresql/):

```bash
psql -h <DATABASE_HOST> -U postgres
```

```sql
-- as a superuser
create user unleash with password '<GENERATED_SECRET>';
create database unleash with owner unleash;
```

# Extensions

```sql
\c unleash
create extension "uuid-ossp";
create extension "moddatetime";
create extension "btree_gist";
```

# Migrations

Unleash applies its own schema migrations at startup; there is nothing to run here.
See [Unleash deployment](https://docs.cyverse.org/deployment/05-core-services/unleash/).
