Incompatibility with better-auth: @neondatabase/serverless requires tagged-template syntax, breaking drizzle-orm/neon-http integration

Hi Neon team,

We tried to integrate the better-auth service to handle auth in our api, but we keep hitting this runtime error introduced to the 1.0.0 update of @neondatabase/serverless package. We are using drizzle-orm/neon-http as the orm for our database

Since betterAuth doesn't use Tagged-template composability in order to run their queries, whenever I hit an auth endpoint we receive the following error from the Neon client library:

[wrangler:inf] OPTIONS /api/auth/sign-up/email 204 No Content (10ms)
✘ [ERROR] # SERVER_ERROR:  Error: This function can now be called only as a tagged-template function: sql`SELECT ${value}`, not sql("SELECT $1", [value], options). For a conventional function call with value placeholders ($1, $2, etc.), use sql.query("SELECT $1", [value], options).

[wrangler:inf] POST /api/auth/sign-up/email 500 Internal Server Error (17ms)

Steps to reproduce

1 - initialize db connection

import { betterAuth } from "better-auth"
import { neon, neonConfig } from "@neondatabase/serverless";
import { drizzle } from "drizzle-orm/neon-http";
import { drizzleAdapter } from "better-auth/adapters/drizzle";
import * as authSchema from "@/db/pg/schema/auth";

const sql = neon(connectionString);
const db = drizzle({ client: sql, schema: authSchema });

export const auth = betterAuth({
  emailAndPassword: {  
    enabled: true
  },
  database: drizzleAdapter(db, {
    provider: "pg",
    schema: authSchema,
    usePlural: true,
  })
});

Expected result

We expected @neon/serverless to be able to support the way pg driver and better-auth are calling the tagged-template function, since libraries who supports neon does not support Tagged-template composability since it's relatively new.

Environment / Packages involved

• [1.0.1] @neondatabase/serverless
• [0.38.4] drizzle-orm/neon-http
• [1.3.4] better-auth/adapters/drizzle

Reproduce the failure with @neondatabase/serverless 1.0.1, drizzle-orm/neon-http 0.38.4, and better-auth 1.3.4. Start at the Neon client path around index.mjs:1276 and the Drizzle call at session.ts:68. Done means the shown better-auth integration can execute its conventional query calls without the tagged-template runtime error.
