Before submitting a pull request, please take a look at our
Contributing guidelines and verify:

• If you've added code that should be tested, please add tests.
• Ensure your code lints and the test suite passes (yarn lint) & (yarn test).

Background

• auto database instrumentation fails out of the box with esbuild - see "mod.require is not a function" in database tracing integrations #3293 (comment)

Proposal

• Allow consumers to pass resolved module for instrumentation directly
• This mirrors sequelize dialectModule

Alternatives

• If there's a way to configure esbuild similar to the webpack commonjsMagicComments, that should do the trick
• However the proposed solution in this PR seems more robust, especially as more bundlers/minifiers are gaining traction

Thanks @aldenquimby!

pkg.native?.Client is now nullable to align with @types/pg. Unfortunately TS is not great with multiple boolean conditions. The changes here were the least disruptive I could come up with
