Sandbox javascript build further

postgresql was failing to find configuration, add it to the sandbox.

When building JS, we were getting the following error:
  [!] RollupError: Node tried to load your configuration file as CommonJS
  even though it is likely an ES module. To resolve this, change the
  extension of your configuration to ".mjs", set "type": "module" in your
  package.json file or pass the "--bundleConfigAsCjs" flag.

Rename the configuration to be mjs to make it happy, and fix other leaks
found at the same time.
