Assuming you run docker-compose with the default postgress credentials and have the dump in cwd as ./dump.sql, execute:
Find current schema name:
Drop database:
```
echo "SELECT CURRENT_SCHEMA, CURRENT_SCHEMA();" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus"
```
> current_schema | current_schema
> ----------------+----------------
> public | public
> (1 row)
Drop schemata (loses all data):
```
echo "DROP SCHEMA public CASCADE;" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus"
echo "DROP SCHEMA tiger CASCADE;" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus"
echo "DROP SCHEMA tiger_data CASCADE;" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus"
echo "DROP SCHEMA topology CASCADE;" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus"
```
> drop cascades to table ...

> DROP SCHEMA
Create the public schema again:
```
echo "CREATE SCHEMA public;" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus"
```
Verify schemata:
```
echo "select schema_name from information_schema.schemata;" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus"
```
Verify database is empty:
```
echo "\dt" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus directus"
```

Create admin role & grant it:
```
echo "CREATE ROLE admin;" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus directus"
docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql -v ON_ERROR_STOP=1 --username directus directus" < ./backend/scripts/drop-database.sql
