[BUG]: PGlite sets process.exitCode = 99

[electrovir]

Describe the bug

Waiting for PGlite to be ready sets process.exitCode = 99. This appears to be happening in the WASM PostgreSQL initialization.

To Reproduce - include code sample(s)

import {PGlite} from '@electric-sql/pglite';

console.log('before:', process.exitCode); // undefined

const pglite = new PGlite('memory://');
await pglite.waitReady;

console.log('after:', process.exitCode); // 99

Logs

N/A

Details

• PGlite version: 0.4.4
• using any extensions?: no
• OS version: macOS
• node, bun, deno or browser version: Node.js

Additional context

This is breaking testing suites for me.

Ai suggests the following fix:

Reset process.exitCode after callMain returns, since the exit code 99 is an internal implementation detail that shouldn't leak to the host process:

const result = this.mod!.callMain(...);
if (typeof globalThis.process !== 'undefined') {
    process.exitCode = undefined;
}
