`deno check <file>` fails since Deno v1.29.0 for vendored deno-postgres

[ChristianSiegert]

Steps to reproduce:

1. Create a .ts file and import deno-postgres:

   // main.ts
   import "https://deno.land/x/postgres@v0.17.0/mod.ts";

2. Run deno vendor main.ts
3. Run deno check --import-map=vendor/import_map.json main.ts

Expected: No errors

Actual: Errors are reported for deno-postgres:

Check file:///<redacted>/main.ts
error: TS2345 [ERROR]: Argument of type 'string | undefined' is not assignable to parameter of type 'string'.
  Type 'undefined' is not assignable to type 'string'.

I just tried it with the latest version; no error was reported, and I could not replicate this. Seems fixed
