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.
