Yeah, the original Percona FDW hasn't been active for a while, only had a few commits after the first release and was missing quite a few features. Also doesn't support anything more recent than Postgres 11.
So the "adjust" CH FDW is the only usable choice today, thankfully quite actively maintained, primarily by the Adjust devs. I'd presume it's used for their production load.
