(duckdb.duckdb.CatalogException) Catalog Error: Type with name REGCLASS does not exist!

[ZmeiGorynych]

When running the code below, I get the following error towards the very end:

[SQL: SELECT pg_catalog.pg_class.relname, pg_catalog.pg_description.description 
FROM pg_catalog.pg_class LEFT OUTER JOIN pg_catalog.pg_description ON pg_catalog.pg_class.oid = pg_catalog.pg_description.objoid AND pg_catalog.pg_description.objsubid = $1 AND pg_catalog.pg_description.classoid = CAST($2 AS REGCLASS) JOIN pg_catalog.pg_namespace ON pg_catalog.pg_namespace.oid = pg_catalog.pg_class.relnamespace 
WHERE pg_catalog.pg_class.relkind = ANY (ARRAY[$3, $4, $5, $6, $7]) AND pg_catalog.pg_table_is_visible(pg_catalog.pg_class.oid) AND pg_catalog.pg_namespace.nspname != $8 AND pg_namespace.nspname = $9 AND pg_catalog.pg_class.relname IN ($10)]
[parameters: (0, 'pg_catalog.pg_class', 'r', 'p', 'f', 'v', 'm', 'pg_catalog', 'main', 'channel_members')]

Running on Windows 10, Python 3.11, fresh install of airbyte with pip.

As a workaround you can downgrade to sqlalchemy 2.0.35

pip install SQLAlchemy==2.0.35

see also Mause/duckdb_engine#1128

That fixed it, thanks!
