It is a tradeoff, e.g. running tests with a real database or other supporting service and taking longer vs. mocking things and having a test environment that is less like reality.

https://testcontainers.com/ is not quite the solution to all your problems, but it makes working with real databases and supporting services pretty much as easy as mocking them would be.
I'd really recommend against mocking dependencies for most tests though. Don't mock what you don't own, do make sure you test each abstraction layer appropriately.
do you really need to test postgres api in your own code?
