Function connectDatabase

connectDatabase(config): Promise<StorageAdapter>
Connect to a PostgreSQL server.

Opens PostgreSQL alone, in every runtime: there is no fallback to a local database, so a server that cannot be reached fails the call. Any connection string pg reads is accepted (a postgres:// or postgresql:// URL, a socket: URL, a socket path).
Parameters
- config: string | PostgresAdapterOptions
Returns Promise<StorageAdapter>
Throws
Error when the configuration names no server: no pool, an empty or unset connection string, and no host, database or user, as connectDatabase(process.env.DATABASE_URL) gives with DATABASE_URL unset. Nothing is opened then; the call does not read DATABASE_URL on its own.
Example
```
// Simple connection string
const db = await connectDatabase('postgresql://user:pass@host/db');

// With full config
const db = await connectDatabase({
  host: 'db.example.com',
  database: 'myapp',
  user: 'dbuser',
  password: process.env.DB_PASSWORD,
  ssl: true
});
```
