[Bug] Error when generating dbt docs

[mrprigun]

I'm trying to generate documentation for the dbt project that works with Greenplum database. The documentation generates but it return non zero exit code, please take a look at the error bellow.

I tried to change driver from greenplum to postgres in my dbt project and it works well without maximum recursion depth exceeded while calling a Python object error. Looks like there is an issue somewhere here dbt/include/greenplum/macros/catalog.sql.

Hi, I'm going to look on this problem, but in greenplum adapter we do nothing with documentation. It looks strange

Do you use partition functionality?

Yep this adapter doesn't do anything with documentation. But if I'll run command dbt docs generate dbt will use this adapter to get db schema and types details. Looks like the adapter is not able to proceed that, but postgres adapter can.

Do you use partition functionality?

No

I have tested dbt docs generate and have no errors. Can you provide simple project to reproduce error?
