[BUG]: `drizzle-kit push` with PostgreSQL leaves behind long-lived connections

### What version of `drizzle-orm` are you using?

0.33.0

### What version of `drizzle-kit` are you using?

0.24.1

### Describe the Bug

Using `drizzle-kit push` wastefully leaves behind long-lived connections with PostgreSQL (`16.4`).

```ts
import type { Config } from "drizzle-kit"

import { env } from "~/env"

export default {
schema: "./src/db/schema.ts",
dialect: "postgresql",
dbCredentials: { url: env.PSQL_URL },
schemaFilter: [env.PSQL_SCHEMA],
} satisfies Config
```

### Expected behavior

Allow a way to configure the client to disconnect after some idle time, or allow more custom code so that the user can manually disconnect the client.

### Environment & setup

- MacOS (`14.6.1`)
