### Describe the Bug

my scheme.ts

```
import { index, integer, pgTable, varchar, text, timestamp, vector, json } from "drizzle-orm/pg-core";
import { EMBEDDING_DIMENSIONS } from "../embedding/consts";

export const myEmbeddingTable = pgTable(
"my_embedding",
{
id: integer().primaryKey().generatedAlwaysAsIdentity(),
name: varchar({ length: 255 }).notNull(),
content: text("content").notNull(),
metadata: json("metadata"),
embedding: vector("embedding", {
dimensions: EMBEDDING_DIMENSIONS
}),
created_at: timestamp("created_at").notNull().defaultNow(),
updated_at: timestamp("updated_at").notNull().defaultNow(),
},
(table) => [
index("embedding_index").using("hnsw", table.embedding.op("vector_cosine_ops"))
]
);
```

then I run `drizzle generate`, it created a `.sql` file but it's missing

```
CREATE EXTENSION IF NOT EXISTS vector;
```

at the first line which will cause error if I run `drizzle migrate`:

```
[⣷] applying migrations...error: type "vector" does not exist
```
