Is there a commonly-used, well-maintained TPC-DS toolset for PostgreSQL? I know some tpcds tools for postgres like gregrahn/tpcds-kit(its tpcds version is 2.x, but the newest tpcds version is 4.x) on GitHub, but I'm curious if there's anything more "official" or widely adopted in the community — something that handles data generation, PostgreSQL-compatible DDL, query adaptation, and result collection out of the box. > > 2.

I try to keep this one maintained and as compliant to the current (4.0) specification as I can: https://github.com/osdldbt/dbt7
I'm not sure how widely used it is, but I believe the OSDL kits are not known to be the easiest to use. :)
Feel free to contact me directly if you have more questions about the kit.
