chore(instrumentation-pg): skip test if db not running

[overbalance]

Which problem is this PR solving?

• Locally I was unable to pass npm run test if the db service was not started.

Short description of the changes

• I copied the guard from the regular test to the ESM version. I have no prior experience with the db packages so please close this if it's off base.

Great catch and thanks for adding the missing code! 😄

@overbalance for some reason is not showing me the option to update with the main before merging, would you mind updating with the latest from main so I can merge it? thanks
