FORMAT function reported as "not existing" with more than two arguments

What happened?

Using FORMAT with more than 2 arguments results in sqlc reporting that no function matching can be found.

FORMAT is a bit of a special case when it comes to the schema definition as Postgres defines it as:

create function format(text, "any") returns text

Even though it is variadic, meaning we can have "any" number of arguments after the first.

If you look at the spec for FORMAT, you should be able to see the difference between the definitions:
https://www.postgresql.org/docs/current/functions-string.html

Relevant log output
