I disagree with removing SQL tests from the worker_spi module. As said
upthread, it makes the worker_spi a fully demonstrable
extension/module - one can just take it, start adding required
functionality and test-cases (both SQL and TAP) for a new module. I
agree that moving to TAP tests will reduce test run time by 1.9
seconds, but to me personally this is not an optimization we must be
doing at the expense of demonstrability.

Having said that, others might have a different opinion here.
