Looks good regarding the macro changes! Something small I noticed was that adapterse/base/relation.py was also updated by dbt-labs/dbt-core#8411 and those changes don't seem to be reflected on this branch: relation.py changes on unit testing branch

I don't entirely recall why/if this change was strictly necessary. I don't see any usage of the method in dbt-core so I suspect it was just a bit of clean-up to reflect the optionality of limit -- but @gshank may have a better recollection (source commit of relation.py changes)

@colin-rogers-dbt Are there any associated tests that also need to move over? Should I look into that as part of the testing migration?

@mikealfare I'm guessing so, I think that will happen naturally as part of the PR to delete dbt-adapter-tests from core/when you break out dbt-postgres

Sounds good. I added an item to our migration list to make sure we don't lose it. So consider the testing half of this feature as out of scope for this PR.

These look like all of the functional code changes from the linked PR.
