This change normalizes Postgres connection URLs that omit the username or hostname so that local development connection strings like postgresql:///mydb behave like libpq/psql and other ORMs. If the DSN omits the userinfo entirely, we default to the OS username; if the hostname is missing, we default to localhost.

Normalize missing username to OS user when original DSN did not include @.
Normalize missing hostname to localhost.
Preserve parsing and validation errors as before.

This fixes issue #8230 where Prisma reported Datasource "db": PostgreSQL database "mydb"... at "undefined:5432" and Postgres received an empty username.

Summary by CodeRabbit

Bug Fixes
- PostgreSQL connection URLs now automatically fill in a missing username using the current system user.
- URLs with an empty hostname now default to localhost.
- Username detection now correctly handles @ characters in paths, queries, and fragments.
- Invalid URLs or unavailable system user information continue to be handled gracefully without preventing connections from using the original URL.

📝 Walkthrough

Walkthrough

PostgreSQL URL validation now defaults missing usernames to the OS username and missing hostnames to localhost. It preserves the trimmed URL when parsing or username lookup fails.

Changes

PostgreSQL URL normalization

Layer / File(s)	Summary
Normalize missing PostgreSQL URL fields `packages/3-extensions/postgres/src/runtime/binding.ts`	`validatePostgresUrl` now calls a normalization helper. The helper uses the OS username when authority userinfo is absent, uses `localhost` when the hostname is empty, and limits `@` detection to the authority segment.

Merge Risk: ⚪ Minimal · up to 3b14c

PostgreSQL URLs missing a username or hostname now receive local defaults, enabling local development connection strings without an explicit user or host. No current merge-blocking risk remains.
