Workers using pg library unable to parse Postgres database DSN

This incident has been resolved. Any impacted developers should update their npm dependencies to use wrangler@3.44.0 or newer, pg@8.11.5 or newer. (In the rare case when an application depends on pg-connection-string directly, this package should also be updated to version 2.6.4 or newer).

We have identified an incompatibility issue with the latest 2.6.3 version of the pg-connection-string library used by the node-postgres library and the Node.js polyfill used by the Workers runtime. This may also impact other libraries that require the Node.js "url" package. This will result in a runtime error related to the URL constructor with the text URL is not a constructor. A fix to the way this is polyfilled is in-progress. In the meantime, users can choose to downgrade to pg-connection-string version 2.6.2 and pg version 8.11.3, which does not import the "url" package.

We are continuing to investigate this issue.
