[BUG]: PGlite failed to initialize properly on v0.5.1

[seepine]

Describe the bug

The same code runs normally in PGlite version 0.4.6, but throws an error after upgrading to version 0.5.1.
The error persists even when running in a brand new Docker environment with no residual old data, ruling out issues caused by legacy data.

To Reproduce - include code sample(s)

1. add pglite.ts

import { PGlite, type PGliteOptions } from '@electric-sql/pglite'

// @ts-ignore
import wasmPath from 'node_modules/@electric-sql/pglite/dist/pglite.wasm' with {
  type: 'file',
  embed: 'true',
}

// @ts-ignore
import initdbWasmPath from 'node_modules/@electric-sql/pglite/dist/initdb.wasm' with {
  type: 'file',
  embed: 'true',
}

// @ts-ignore
import dataPath from 'node_modules/@electric-sql/pglite/dist/pglite.data' with {
  type: 'file',
  embed: 'true',
}

export async function createPGlite(dataDir: string, options?: PGliteOptions): Promise<PGlite> {
  // Read the embedded files
  const [wasmBuffer, initdbBuffer, dataBuffer] = await Promise.all([
    Bun.file(wasmPath).arrayBuffer(),
    Bun.file(initdbWasmPath).arrayBuffer(),
    Bun.file(dataPath).arrayBuffer(),
  ])
  // Create PGlite instance with pre-loaded modules
  const db = await PGlite.create(dataDir, {
    ...options,
    pgliteWasmModule: await WebAssembly.compile(wasmBuffer), // not `wasmModule`
    initdbWasmModule: await WebAssembly.compile(initdbBuffer),
    fsBundle: new Blob([dataBuffer]),
  })
  return db
}

2. index.ts

import { migrate as pgliteMigrate } from 'drizzle-orm/pglite/migrator'
import * as schema from './schema'

const client = await createPGlite(".pglite")
const db = pgliteDriver({ client, schema, casing: 'snake_case' })
await pgliteMigrate(db, { migrationsFolder: './drizzle' })

3. Dockerfile

FROM oven/bun:alpine AS build
COPY package.json bun.lock bunfig.toml ./
RUN bun ci
COPY ./ ./
RUN bun build --compile index.ts --outfile dist/app

FROM alpine:3.23
WORKDIR /work
RUN mkdir /data
RUN apk add --no-cache libstdc++ 
ENV DATABASE_URL="/data/pglite.data"
COPY --from=build /work/dist/app /work/app
COPY --from=build /work/drizzle /work/drizzle
ENTRYPOINT ["./app"]
