The getting started tutorial has a couple of issues. Example:

% meltano config target-postgres set add_metadata_columns True
>/Users/work/.local/pipx/venvs/meltano/lib/python3.11/site-packages/meltano/core/settings_service.py:478: RuntimeWarning: Unknown setting 'add_metadata_columns'
  warnings.warn(f"Unknown setting {name!r}", RuntimeWarning)
Loader 'target-postgres' setting 'add_metadata_columns' was set in `meltano.yml`: 'True'

@danylo thanks for letting us know! It looks like that setting is from the transferwise variant and the tutorial is using the meltanolabs variant now

I'm also having some trouble with part 3...

fyi @Sven Balnojan

@danylo to fix the original issue you ran into you can run

meltano lock loader target-postgres --update

to pull in the missing setting. But its actually called

add_record_metadata

vs

add_metadata_columns

which was originally in the guide. Theres a PR open to fix that incorrect reference.
