Yeah, but at the top of this page, there is this text: "This was never integrated into PostgreSQL, and requires significant work to be production quality".
If I used update syntax it would long implement for this query. I'm not a developer and I'm new to Postgres. Is there a good document you suggest me to use?

To call him a dog hardly seems to do him justice though in as much as he had four legs, a tail, and barked, I admit he was, to all outward appearances. But to those who knew him well, he was a perfect gentleman (Hermione Gingold)
> What happens when you run the statement through psql?
It will fail, of course, since there's no MERGE statement in Postgres.
I think the reason for the weird error is that the plpgsql scanner is seeing the "INTO cidrdba.sc_date_in" part and trying to process that as an "INTO plpgsql-variable" clause, before it's fed the rest of the statement to the core parser, which is what would notice that MERGE isn't a known command. Maybe we could improve matters by reordering that processing, but it might be a lot of work for a small benefit.
